BACKGROUND
BACKGROUND
__________


In 1978, the United States Navy converted the U.S.S.

ARTHUR M. HUDDELL, a World War II Liberty Ship, into a non-

motorized barge for storing and transporting maritime cable

purchased by the Navy from Simplex Wire and Cable Co. The

retrofitted HUDDELL was towed to Simplex's facility at Newington,

New Hampshire, for cable loading in May 1979, where it remained

moored for two years.

The cargo hold had been adapted to house several round

tanks, recessed sixteen feet into the 'tween deck. Simplex hired

temporary employees known as cable loaders to descend into

these tanks from the 'tween deck for the purpose of winding the

incoming "wet" cable in concentric layers onto a spool. During

the HUDDELL's retrofitting, the Navy installed a nonremovable

metal barrier around Tank 4 to prevent workers on the 'tween deck


2
2














from falling into the tank. The barrier included two uninter-

rupted safety railings located at the top of an access ladder

attached to the interior wall of the tank to permit access to and

from the tank floor. In order to exit the tank, a cable loader

would climb to the top rungs of the ladder, at which point three

options were available for getting from the tank onto the 'tween

deck floor: (1) holding onto a "grab bar," which was attached to

the 'tween deck floor and located six inches from the outside

edge of the tank, then crawling forward and passing under the
_____

lower railing and between the vertical stanchions supporting the

two railings; (2) stepping in a crouched position between the
_______

lower and upper railings of the barrier; or (3) climbing over the
____

top railing located approximately five feet above the 'tween deck

floor.

At the time Simplex hired Keller as a cable loader, he

was a nonmatriculating sophomore at the University of New

Hampshire. On the night of November 4, 1979, Keller went to a

bar, where he and his friends drank approximately 120-160 ounces

(or two six-packs) of beer between 10:00 p.m. and 11:20 p.m.

Keller reported for work at about 11:30 p.m., and was assigned to

Tank 4 for the first time. He and several coworkers climbed down

the ladder from the 'tween deck into Tank 4 without incident,

where they loaded cable until 2:00 a.m.

When it came time for a work break, Keller climbed to

the top of the ladder, and, according to coworker Rhonda Rossley,

grabbed the lower safety railing with his left hand and placed
____


3
3














his left foot on one of the two top rungs of the ladder. Then,
____

as he began to raise his right leg, he fell backward, neither

attempting to regain his purchase nor crying out, and plummeted

to the tank floor sixteen feet below, landing on his head. When

a Simplex foreman administered first aid, he detected the odor of

alcohol. A blood-alcohol test taken at 3:00 a.m., some three and

one-half hours after Keller had reported for work, revealed a .14

blood-alcohol level, well above the .10 prima facie blood-alcohol

level for demonstrating that a motor vehicle operator is under

the influence. See N.H. Rev. Stat. Ann. 262.A-63 (1963)
___

(amended 1994, lowering limit to .08). Since the fall, Keller

has remained amnesiac as to all events surrounding the accident.

Following a seven-day bench trial on Keller's claims

against the United States for negligently installing "unsafe"

lighting and railings and an "unsafe" ladder in Tank 4, and for

failing to warn Simplex workers of the potential danger, see 33
___

U.S.C. 905(b), the district court ultimately awarded judgment

to the United States. See Keller v. United States, No. 81-549-SD

would strike his head; and (3) no warning of these protrusions
was posted on the ladder.

judgment deprive the trial court findings of the customary

erroneous factual findings, or fail to make required findings,

see Fed. R. Civ. P. 52(a), regarding the alleged breach of the

vessel owner's "turnover" duties of care? Third, did the dis-

trict court misdefine a vessel owner's "continuing" duty to

inspect or supervise cargo loading operations for developing

hazards?


A. The Decision-making Delay
A. The Decision-making Delay
_________________________

First, Keller claims that an unprecedented eight-year

delay between trial and the entry of judgment, coupled with the

trial judge's failure to refresh his recollection through re-

course to a complete trial transcript prior to making findings of

fact, resulted in a violation of his constitutional right to

"access to the courts" and to due process, see U.S. Const.
___

____ ______

customary appellate deference accorded trial court findings. Cf.

889 F.2d 1205, 1209 (1st Cir. 1989) (excusing two and one-half

district court findings, see infra Section II.B, to this extended
___ _____

decision-making delay, and implicitly relies on a conclusive

presumption that the court was unable to make more complete and

detailed findings as it could not recall the evidence presented

at trial almost eight years earlier.

Keller concedes that neither Chamberlin nor Fernberg
__________ ________

concluded that prolonged decision-making delay, per se, requires
___ __

vacatur. Nor has he cited authority for a per se rule fixing an
___ __

outer limit on decision-making delay. Cf. Ad Hoc Comm., 488 F.2d
___ ____________

at 1244 (rejecting per se rule under Federal Constitution for

____ _____________________________ ______________

697, 705-06 (9th Cir. 1992) (conducting ad hoc inquiry to deter-
__ ___

mine whether pretrial delay "exceed[ed] constitutional bound-

aries").

There are sound reasons for abjuring a per se rule even
___ __

in cases involving plainly excessive delay. In the first place,

ad hoc appellate scrutiny is indispensable to the core deter-
__ ___

mination whether delay rendered the decision unreliable. Second-

ly, it is highly doubtful that direct appellate review affords

"an effective means of enforcing district court timeliness." See

_______________ _________________________

(9th Cir. 1989) (delay approximating four years), cert. denied,
____ ______

112 S. Ct. 1283 (1992). Thirdly, remands for reconsideration or


6
6














retrial yield yet further delays, exacerbating the burdens on

litigants. For these reasons, and notwithstanding our parallel

supervisory responsibility, see, e.g., 28 U.S.C. 1651 (mandamus
___ ____

jurisdiction); Petition of Henneman, 137 F.2d 627, 630 (1st Cir.
_____________________

1943), we consider it critically important that appellate atten-

tion remain focused on ensuring that trial court findings,

despite inordinate decision-making delay, not be squandered

unless their reliability has been undermined. We therefore opt

for careful de novo scrutiny of the entire record with a view to
__ ____

whether the prolonged delay in reaching a decision rendered the

trial court's findings of fact unreliable to the degree that

vacation of its judgment is warranted despite the admittedly

severe impediments to reliable fact-finding in the event of a

remand for new trial. Cf. Barker v. Wingo, 407 U.S. 514, 532
___ ______ _____

(1972) (long pretrial delays threaten to impair criminal defense,

lest witnesses die, disappear, or suffer memory loss or distor-

tion).

Notwithstanding the eight-year interval between trial

and judgment, for which we have been unable to glean adequate

explanation, neither Keller nor the record on appeal suggests

that the district court did not perform its decision-making

responsibility with care. As Keller's several requests to

expedite the decisionmaking process acknowledge, the district

court was in no sense indifferent to its responsibility to render

a decision but encountered extraordinary docket pressures at the

same time it was required to give precedence to its criminal


7
7














caseload. See Speedy Trial Act, 18 U.S.C. 3161 (1993).
___

Nor would we well serve the interests of justice, or

the integrity of the decision-making process, were we to presume

that the absence of a complete trial transcript rendered the

district court incapable of determining matters relating to

witness demeanor and credibility, or to recollect or reconstruct

trial testimony, through other reliable means (viz., trial notes,
___

voluminous trial exhibits). See Keller, No. 81-549-SD, slip op.
___ ______

at 16 ("The court in the course of rendering its decision has

reviewed all of the exhibits . . . ."). After all, the responsi-

bility incumbent on an appellant to substantiate a challenge to

the sufficiency of trial court findings is not met merely with

conclusory allegations that the trier of fact could not have

recalled or reconstructed the evidence without a complete trial

transcript. Moreover, this case does not require us to speculate

as to the reliability of the trial judge's findings, since a

complete trial transcript is available for the purpose. Thus, as

regards the claim that the trial judge's findings themselves

evince prejudice from the extended decision-making delay, we test

Keller's thesis as in any other case, by inquiring whether the

findings were infected with "clear error" based on our own

painstaking scrutiny of the entire trial record, including a

complete trial transcript. See Interstate Commerce Comm'n v.
___ ___________________________

B. The Merits
B. The Merits
__________

The district court made seven findings central to the

merits-related challenges advanced on appeal:

(1) Keller was a "longshore worker" to whom defendant
owed a duty of "ordinary care," under LHWCA sec-
tion 905(b),2 to provide a vessel in such condi-
tion that "an expert and experienced stevedore
[would] be able to exercise reasonable care to
carry on its cargo operations with reasonable
safety," and a duty to warn the stevedore of any
latent safety defects on the vessel not reasonably
discoverable by an "expert and experienced" steve-
dore, Keller, No. 81-549-SD, slip op. at 9-10
______
(quoting Scindia Steam Navigation Co. v. de los
______________________________ ______
Santos, 451 U.S. 156, 166-67 (1981));
______

(2) Defendant's expert witness, Jan Bijhouwer, relying
on "applicable" maritime safety standards in for-
mulating his opinion that the HUDDELL's ladder
design was "safe," proved "more persuasive" than
plaintiff's competing expert, id. at 13;
___

(3) No eyewitness observed the precipitating cause of
the fall (e.g., whether Keller hit his head on a
____
safety rail), id. at 11-12;
___


____________________

2Section 905(b) provides in pertinent part:

In the event of injury to a person covered
under this Act caused by the negligence of a
vessel, then such person . . . may bring an
action against such vessel as a third party .
. . , and the employer shall not be liable to
the vessel for such damages directly or in-
directly and any agreements or warranties to
the contrary shall be void. . . . The liabil-
ity of the vessel under this subsection shall
not be based upon the warranty of seaworthi-
ness or a breach thereof at the time the
injury occurred.

33 U.S.C. 905(b).

(4) Even if the design of the ladder deviated from
"applicable" maritime safety standards in certain
respects, there was insufficient evidence that
these deviations caused Keller's fall. No other
______
accidents occurred on this ladder, despite the
fact that no less than twelve persons climbed up
or down the ladder under identical conditions
immediately prior to and after Keller's accident,
___________
id. at 13;
___

(5) Keller's blood alcohol level of .14, see supra at
___ _____
p. 4, might have been a "significant [causal]
factor" in the accident, Keller, No. 81-549-SD,
______
slip op. at 15;

(6) If any design deviation constituted a potential
"hazard," such hazard was obvious (i.e., not la-
____
tent), and could be "anticipate[d]" by a stevedore
"if reasonably competent in the performance of his
work," id. at 13-14; and
___

(7) Even if custom had required that defendant place a
representative aboard the HUDDELL to monitor cargo
loading, "a custom-generated duty to supervise and
inspect does not transfer to the ship owner a duty
to eradicate dangers reasonably known to and man-
aged by the stevedore," id. at 14.

v. Poulos, 11 F.3d 271, 278 (1st Cir. 1993). Keller claims that
______

by failing to distinguish between "turnover" and "continuing"

duties, the district court misconstrued the standard of care

incumbent upon a vessel owner under LHWCA 905(b).

As it pertains to Keller and Simplex, in its current

10
10














incarnation the LHWCA is a strict liability statute. A longshore

or harbor worker such as Keller, who incurs a work-related

injury, may recover disability and medical compensation from the

stevedore-employer (viz., Simplex) even though the stevedore was
____

not at fault. Conversely, an award of compensation under the

LHWCA, such as Keller recovered from Simplex, is the longshore

worker's exclusive remedy against the stevedore-employer. See 33
_________ ___

U.S.C. 904, 905(a); Williams v. Jones, 11 F.3d 247, 250 n.1
________ _____

(1st Cir. 1993).

Until 1972, an injured longshore worker could sue the

vessel owner on two distinct legal theories: negligence and
______ _____

breach of the warranty of "seaworthiness." "Unseaworthiness"

could be established more easily than negligence, simply by

showing that some condition or appurtenance on board the vessel

at the time of the accident was unreasonably hazardous, even if

the stevedore-employer was the sole cause of the hazard. See
___

owners thus became virtual insurers of the on-board safety of

longshore workers. Although the only legal recourse available to

the nonnegligent vessel owner was an indemnification claim

against the stevedore-employer, even that remedy was unavailable

unless the hazardous condition or appurtenance was due to the

stevedore's negligence. In 1972, the LHWCA remedial

scheme underwent dramatic adjustment. Congress greatly increased


11
11














the amount of compensation recoverable from the stevedore-employ-

er, repudiated the warranty of "seaworthiness" as a basis for

third-party actions against the vessel owner, required the

injured longshore worker to prove negligence on the part of the

vessel owner, and precluded a negligent vessel owner from obtain-

ing indemnification from the stevedore-employer. See 33 U.S.C.
___

905(b); supra note 2. These changes were designed "to shift more
_____ _____ ____

of the responsibility for compensating injured longshoremen to
__ ___ ______________

the party best able to prevent injuries: the stevedore-employer."

(emphasis added). Consequently, at the present time the duties

of care incumbent upon a vessel owner fall into two broad catego-

ries: (i) so-called "turnover" duties those which are to be

discharged before the owner consigns the vessel to the stevedore
______

for cargo loading operations and (ii) so-called "continuing"

duties, such as inspection, supervision or intervention, which

may persist after the stevedore commences cargo operations. See
_____ ___

Scindia, 451 U.S. at 166-67, 172-76. There are two distinct sub-
_______

categories of "turnover" duty, depending on whether an unreason-

ably hazardous condition on board the vessel is patent or latent.




(i) The Vessel Owner's "Duty of Safe Condition"
(i) The Vessel Owner's "Duty of Safe Condition"

to monitor the vessel workplace for safety. On the other hand,

because longshoring is particularly dangerous, in many respects

inherently so, see Johnson v. A/S Ivarans Rederi, 613 F.2d 334,
___ _______ __________________

339 n.5 (1st Cir. 1980), few on-board appurtenances would ever

satisfy such an exacting threshold. Accordingly, the "foresee-

ability" standard to which a vessel owner is held under its "duty

of safe condition" has been relaxed: "ordinary care under the

circumstances" now governs the owner's discharge of its duty to

turn the vessel over "in such condition that an expert and
______ ___

experienced stevedoring contractor, mindful of the dangers he
___________ ___________ __________

should expect to encounter, arising from the hazards of the
______ __ _________

ship's service or otherwise, will be able by the exercise of

Unlike the vessel owner, however, the stevedore is

subject to detailed legislative and administrative prescriptions

for affording its workers a "safe" workplace. See, e.g., 33
___ ____

(1993) (implementing regulations for "ladders"); see also Scin-

dia, 451 U.S. at 170. Thus, a vessel owner "reasonably" may rely
___

on the stevedore-employer's supervision of its own employees in

their interaction with and avoidance of "obvious" or "anticipat-

ed" hazards foreseeably associated with stevedoring on board the

owner's vessel. See, e.g., Polizzi v. M/V Zephros II Monrovia,

argues that the court focused its factual inquiry exclusively on

agree. Though neither the district court, nor for that matter

the Scindia Court, used the term "turnover duty," the district
_______

court focused directly on the two issues material to the perti-

nent inquiry: (i) "[c]entral to the issue of legal fault in this

issue was causally defective," in light of "applicable safety

standards" and other evidence proffered by Keller, Keller, No.
______

81-549-SD, slip op. at 13, and (ii) whether "the notice given by

the presence of any such hazard" rendered it obvious, id. at 14.

Thus, the district court clearly identified and applied the

proper duty of care. We turn then to examine its factual find-

ings.


b. Factual Findings on "Turnover" Duties
b. Factual Findings on "Turnover" Duties
_____________________________________

Keller asserts two challenges to the district court

finding that the United States did not breach its turnover

duties. First, he argues that the pivotal finding that the

testimony of Jan Bijhouwer, defendant's expert witness on marine

design, was "more persuasive" than the testimony of plaintiff's

expert is so conclusory that no evidentiary basis for the

finding can be gleaned from the record. See Fed. R. Civ. P. 52
___

("In all actions tried upon the facts without a jury . . . the

court shall find the facts specially and state separately its
_________

conclusions of law thereon . . . .") (emphasis added).

15
15














The crux of our ad hoc Rule 52(a) inquiry is whether
__ ___

the trial court findings are precise and detailed enough to

enable effective appellate review. See Knapp Shoes, Inc. v.
___ __________________

Sylvania Shoe Mfg. Corp., 15 F.3d 1222, 1228 (1st Cir. 1994). As
________________________

long as the factual bases essential to the court's special

findings are reasonably discernible from the record, the dictates

of Rule 52(a) are met. Id. (noting that the "'judge need only
___

make brief, definite, pertinent findings . . . there is no

necessity for over-elaboration of detail'") (citation omitted).

Contrary to Keller's contention, the district court did not begin

and end its analysis with the observation that Bijhouwer's

testimony was "more persuasive," but expressed one very important
_________

rationale for so finding: Bijhouwer was the only expert witness
____

who based his opinion on "applicable [maritime] safety standards"
__________

and on the possible consequences any "deviations" from those

standards might have upon worker safety. Further, the court

proceeded to point out that Keller had produced no competent

evidence that the Tank 4 ladder was defective in any way. These

"special findings" met the Rule 52(a) requirements.

Keller next argues that the trial court's findings

(e.g., that the ladder design was "generally safe," or its
____

hazardous features, if any, should have been obvious to the

stevedore's employees) were based upon inherently unreliable or

inadmissible evidence, or its refusal to admit or consider

competent evidence entitled to greater weight. Whether the

defendant breached a duty of care is a question of fact, which we

Keller challenges the cornerstone finding by the

district court: that Bijhouwer's expert opinion was founded on a

"persuasive" appraisal of "applicable" industry standards. The

gist of Bijhouwer's testimony was that he personally inspected

the Tank 4 ladder after Keller's fall, measured its dimensions,


18
18














and climbed out of Tank 4 several times by pulling himself under
_____

the lower railing with the aid of the metal grab bar mounted in

the 'tween deck floor. In twenty-four years as a marine survey-

or, approximately five to ten percent of the vessels Bijhouwer

had encountered were equipped with ladder-railing configurations

similar to Tank 4. Bijhouwer found the Tank 4 ladder "easy" to

climb, and "perfectly safe." He consulted two fixed-ladder

safety standards governing "shipboard installation as opposed to

land-based installation": the Maritime Administration standard

(MARAD) (1965) and the American Society for Testing and Materials

standard (ASTM) (1983). In Bijhouwer's opinion, both standards

confirmed that the Tank 4 ladder-railing design met or surpassed

applicable maritime safety standards.3

Finding no merit in Keller's other challenges to the

district court's credibility determinations,4 we focus on two

____________________

3Minor measurement "deviations" between MARAD-ASTM and Tank
4 included, inter alia: the facial width of ladder rungs (slight-
_____ ____
ly over 14 inches; standard 14 inches); rungs (1-1/2 inches by
1/2 inch; standard 3/4 inch by 3/4 inch); and toe clearance
behind rungs (5 inches at sides, 14 3/4 inches in middle; stan-
dard minimum 5 inches).

4For example, Bijhouwer testified that a person who was
exiting Tank 4 for the first time might be able to do so "blind-
folded." Keller characterizes this testimony as patently in-
credible, especially in view of other testimony that Tank 4 was
"more difficult" to exit than the tanks on other vessels (e.g.,
____
the FURMAN) then moored at Simplex. On redirect, however,
Bijhouwer clarified that the ladder and grab bar combination
installed in Tank 4 was so well designed that, after one trip up,
_____ ___ ____ __
a climber could use it "blindfolded." Bijhouwer's redirect
testimony would enable a reasonable inference that Simplex, once
_______
it became acquainted with the Tank 4 configuration following
turnover, was in no sense disabled from informing its employees
about at least one safe method of exiting the tank. Moreover,
the fact that other witnesses testified that the Tank 4 ladder

related contentions. First, Keller quarrels with the district

court ruling that ASTM was an "applicable" industry standard. He

points out that the ASTM was promulgated several years after

Keller's fall, for the purpose of facilitating inter-vessel

exchangeability of component parts, rather than promoting safety

concerns. And, because Bijhouwer conceded at trial that MARAD

required an unobstructed gap in the Tank 4 railing, Keller
___

contests the district court ruling that MARAD was an "applicable"

industry standard and disagrees that the Tank 4 ladder substan-

tially conformed with the MARAD design.

These contentions cannot withstand scrutiny. Keller

does not explain why a maritime safety standard like ASTM would

be wholly "inapplicable" simply because it had been promulgated
______

after the accident. In this context, "applicability" connotes no

statutory or regulatory compulsion to conform with a particular
_______

standard. See infra note 5. Rather, "applicability" connotes
___ _____

mere relevance: that ASTM had some tendency to make it more or

less likely that the defendant and Simplex would have regarded
___

the ASTM norm as a minimum safety standard for the industry.

There is no evidence that general maritime safety standards

changed so dramatically between 1979 and 1983 that ASTM was

rendered wholly immaterial as an indicator of 1979 industry

was "more" difficult to climb did not compel a finding that it

safety practices, see Fed. R. Evid. 401, nor that ASTM was based
___

exclusively on post-1979 data. Further, in response to Keller's

contention that ASTM's purpose was merely to facilitate the

interchangeability of component parts, we note Bijhouwer's

testimony that though the maritime standards he relied upon

(including ASTM) might not be exclusively safety-oriented, there
_________ ____ ___________

were "safety-related aspects to all of [these industry] stan-
___

dards." Thus, it was not clear error to find that ASTM possessed

some probative value in determining industry safety practices in

1979.

Even if ASTM were deemed wholly "inapplicable," howev-

er, it was but one of two independent maritime safety standards
___ ___ ___________

on which Bijhouwer relied. Keller therefore would have had to

hobble both the ASTM and the MARAD standards in order to prevail.
____ ___ ___ _____

Viewed as an enumeration of minimum safety recommendations for
_______

the industry, MARAD is conspicuously silent on many matters
______

Keller considered pertinent to the defendant vessel owner's duty

of care, including any unequivocal recommendation that a gap be

left in safety railings which extend around the top of a fixed

ladder. Bijhouwer testified that MARAD recommended such a gap

(or removable railings) only as needed to facilitate cargo

loading via the deck on which the railings are located. Here, of
___ ___ ____ __ _____ ___ ________ ___ _______

course, the cable was not loaded into Tank 4 across the HUDDELL's
______

'tween deck where the safety railings were located, but from the

main deck, down through an upper hatch and into Tank 4. He

further testified that MARAD recommends such an "access opening"


21
21














only in "deck" railings near ladders, citing two plausible

reasons that this would not indicate that a complete gap should
________

have been left in the Tank 4 railings: (1) the MARAD provision

refers exclusively to railings on the periphery of the main or

weather deck of the vessel, not to railings on lower decks, like

the 'tween deck; and (2) the undefined term "access opening"
_________

might reasonably mean any aperture through which a person could

exit safely, such as the 27-inch space under the lower railing on
_____

Tank 4. Bijhouwer's testimony likewise was bolstered by OSHA

regulations, which presumably impose a heightened obligation on
__________

the stevedore to provide its employees with a "safe" workplace.

See 33 U.S.C. 941. Yet even the OSHA standards do not dis-
___

courage the ladder configuration found on Tank 4. See 29 C.F.R.
___

1918.25. Thus, Keller failed to weaken Bijhouwer's interpreta-

tion and application of MARAD.

To the extent that the technical aspects of MARAD

invited expert interpretation, the district court was entitled to

rely on Bijhouwer's testimony, especially since Keller tendered

no persuasive counter-interpretation:

Compliance with the customs and practice of

per se. And in fact, the OSHA standards were not directly

applicable to defendant, because (1) they do not pertain to

___
U.S.C. 941; 29 C.F.R. 1918.1-1918.106; and (2) they regulate

safety codes are necessitated by the unique spatial and weight

constraints on working maritime vessels. The van Dissell bench-

marks undoubtedly set more stringent safety specifications than

the MARAD model, and thus were relatively "safer," but Scindia
__________ _______

inquires only whether Simplex could have anticipated that the
___________

vessel owner would consign a vessel with these heightened land-

based safety specifications. By contrast, Bijhouwer testified

that shipyards commonly consult standards, such as MARAD, in
________ _______ _____

designing and constructing merchant vessels, rather than the more
______ ____

generalized military specifications like MIL-STD-1472; and,

further, that he had encountered the Tank 4 ladder configuration

in at least five to ten percent of the merchant vessels he had

surveyed.

Second, Keller attacks, as internally inconsistent and

inherently implausible, the Bijhouwer testimony that the 27-inch

space beneath the lower safety railing on Tank 4 afforded an
_______

adequate "access opening" according to MARAD. Bijhouwer testi-

fied on deposition that a minimum vertical gap of twenty-five

inches beneath the lower railing would be a "safe" "access

opening" for exiting Tank 4. At trial, however, Bijhouwer

conceded that the grab bar, which was 4 1/8 inches high, was set

into the 'tween deck floor six inches from the ladder and the rim

of Tank 4. Confronted with this configuration indicating an

actual clearance of 22 7/8 inches Bijhouwer nonetheless stated

that the grab bar posed no hazardous interference. He explained

that there would remain at least a 25-inch clearance directly
________


24
24














beneath the lower railing where it passed over the six-inch ledge
_______ ___ ________ _____

of the tank, and that this clearance was needed only to accommo-
__ ___ ____

date the height of the climber's body as he placed his knee up

onto the tank ledge.6 In that position, the climber would

attain maximum vertical posture (measured from stooped
_______

head/shoulders to knee), at which point his body would flatten

out to less than twenty-five inches as he pulled himself forward
_______

and through the narrower opening between the top of the grab bar
_______

and the lower railing.7 While Keller characterizes these

movements as dangerously acrobatic, it is well recognized that

longshore workers are called upon to cope with uncomfortable,

cramped positions in the close confines of a vessel. See, e.g.,
___ ____

Bjaranson, 873 F.2d at 1208 ("the men, according to the testimo-
_________

ny, could have squeezed around the leg of the crane" to avoid the
________


____________________

6Keller argues that the method of egress endorsed by Bij-
houwer was unmanageable because the climber would have to place
his knee on a narrow coaming that raised 7/8 inches at the edge
of the tank, which Bijhouwer conceded would "cut" into the
climber's knee. In fact, however, Bijhouwer testified that a
climber could place his knee "momentarily" between the coaming
_______
and the grab bar, not on top of the coaming. When asked if the
___ __ ___ __ ___ _______
coaming would then "dig[] into your knee," Bijhouwer simply
responded that "[y]ou can feel the coaming."
____

7Keller likewise relies on Bijhouwer's admission that at the
time he first formulated his opinion that the ladder design was
safe, he had not considered the actual conditions (e.g., wet,
____
cold, artificial lighting) in Tank 4 on the night of the acci-
dent. Nevertheless, when asked at trial, Bijhouwer testified
that those conditions did not alter his opinion as to the safety
of the ladder design. He explained, for example, that even
though Keller was wearing heavy clothing at the time, the clear-
ance beneath the lower safety railing would be adequate for a
climber emerging from the tank, because clothing might catch on

the railing only as a climber was backing into the tank, not as

hazard) (emphasis added). Further, Bijhouwer testified that the

lower railing served both (i) a safety function, since it would

protect an exiting climber from falling backward into the tank,

and (ii) a utilitarian purpose, since it would provide Simplex
___

with the option to spool wire into Tank 4 above the 'tween deck
_____

level. See Johnson, 613 F.2d at 348 (trier of fact may consider
___ _______

"the usefulness to the [vessel] of the [allegedly] dangerous
__________

condition") (emphasis added); see also Miller, 851 F.2d at 205
___ ____ ______

("The court found that the toolbox was a necessary piece of
_________ _____ __

equipment for the barge and that it was situated reasonably to
_________

keep it out of the way of the workers on the barge. . . . Simi-

larly, the court found that whatever hazard was presented by the

counterweight was justified by its important safety purpose of
_________ ______ _______

keeping the toolbox lid from snapping shut unexpectedly.")

(emphasis added).

According to Bijhouwer, therefore, the Tank 4 ladder

incorporated at least one "safe" method of egress compatible with

MARAD (i.e., "under" the lower safety railing); hence, the vessel
____

owner had not provided Simplex with an "unavoidably" hazardous

ladder. See Teply, 859 F.2d at 378. Thus, even if MARAD had
___ _____

been the only "applicable" industry standard on which Bijhouwer

could rely, it afforded sufficient support for the district court

finding that the defendant vessel owner had discharged its

turnover duty of safe condition, on the ground that Simplex

should have "anticipated" and managed the equipment as designed,

whatever its inherent, but avoidable, risks.
___ _________


26
26














Keller further contends that the trial court erred in

finding that any potential risks attending the use of the Tank 4

ladder were "obvious." He relies on (i) Bijhouwer's testimony

that it would be "reckless" for Simplex employees to attempt to

exit Tank 4 by passing between the two safety railings or "over"

the top railing, and (ii) evidence that Simplex employees contin-

ued to use both these methods after turnover. Keller argues that

this latent design "defect" generated the independent turnover

duty that the vessel owner warn Simplex or its longshore workers
____

of the hidden danger. This contention, too, is flawed.

First, Keller incorrectly assumes that by adopting

Bijhouwer's testimony that MARAD and ASTM were "applicable"

safety standards, the trial court likewise necessarily credited

Bijhouwer's expert opinion (not based on MARAD) that it would
___

have been reckless to utilize the two other methods of egress.

On the contrary, however, the court did not adopt that portion of

the Bijhouwer testimony but went on to note instead that Keller

had proffered no evidence of any design defect whatsoever in the
___ __________

Tank 4 ladder; for example, that any accident had ever occurred
___

on the ladder when persons other than Keller used these two

alternate methods under substantially similar conditions (wet,

cold, artificial lighting). See, e.g., McKinnon v. Skil Corp.,
___ ____ ________ __________

638 F.2d 270, 277 (1st Cir. 1981) (subject to Rule 403 balancing,

evidence of prior accidents under similar conditions admissible

to show design defect); cf. Martinez, 903 F.2d at 609 (at summary
___ ________

judgment, vessel owner met burden by "offer[ing] evidence that


27
27














during the vessel's seven years of operation no longshoreman ever

fell into one of the ladder openings on the lashing platforms and

no complaints were lodged concerning the platforms"); McGann, 586
______

F. Supp. at 1571 ("[N]o other accidents or complaints concerning

this type of ladder have been reported . . . ."); accord Pittman
______ _______

v. Littlefield, 438 F.2d 659, 662 (1st Cir. 1971) (absence of
___________

other accidents under substantially similar conditions may be

probative of "safe" condition) (applying New Hampshire law).

Second, even if the district court had agreed with

Bijhouwer's assessment of the risks attending the two alternate

methods of egress, Bijhouwer never intimated that those methods

posed hazards not readily foreseeable by Simplex. Scindia, 451
_______

U.S. at 167 (noting that duty to warn exists only if "defect"

"would not be obvious to or anticipated by [stevedore] if reason-

ably competent in the performance of his work"). The alleged

design defect (two fixed railings) was in no sense latent.

Unlike a hairline fracture in the rung of a ladder, for example,

which might render the ladder configuration not reasonably safe

for any unwarned usage, the juxtaposition of the two railings and
___

the absence of posted instructions put Simplex on notice that its

employees, unless instructed otherwise, might attempt to exit

Tank 4 in any of three ways. If Simplex had deemed Bijhouwer's

"under" method the only "safe" one, it could have instructed its

employees not to use the two alternate methods. Or if it consid-

ered all three methods "unsafe," it could have removed the

railings between the stanchions at the top of the ladder.


28
28














Relying on the fact that he was never in Tank 4 prior

to the night of the accident, Keller wrongly presumes that

obviousness and latency are measured by what a relatively inexpe-

rienced longshore worker might observe. Instead, the Scindia
______ _______

standard turns primarily on what an "experienced" stevedore, like

Simplex, reasonably would be expected to notice. By the same
_______

token, if the district court correctly found that even Simplex

longshore workers reasonably could be expected to recognize any
_______

such defects, it surely follows that their more experienced

stevedore-employer should have discovered the defects during the

course of its extended two-year stewardship of the HUDDELL. See
___

Bjaranson, 873 F.2d at 1209 n.7 ("The condition of the ladder was
_________

apparent and obvious when Bjaranson's employer, the stevedoring

contractor, boarded the ship and assumed the control of the cargo

operation. Although the condition may not have been obvious to

Bjaranson at night, the fact that the condition was obvious to
__

his employer eliminated whatever duty there may have been upon
___ ________

[the vessel owner] to warn the individual employees.") (emphasis

added).

Next, Keller contends that the district court improper-

ly considered his blood-alcohol level at the time of the acci-

dent, since the doctrine of pure comparative fault would not

permit contributory negligence to defeat Keller's LHWCA claim,
______

but only to abate damages. See Johnson, 613 F.2d at 347; 1A
___ _______

Benedict on Admiralty 56, at 3-33. First, the district court
_____________________

explicitly acknowledged that had Keller proven that the defendant


29
29














vessel owner was a cause of Keller's accident, the court could
_

not have treated Keller's blood-alcohol level as a total bar to

recovery under the LHWCA. See Keller, No. 81-549-SD, slip op. at
___ ______

15 ("The court is, of course, aware that were negligence found on
____ __________ _____ __

the part of the ship owner, the intoxication of Keller . . .
___ ____ __ ___ ____ _____

would not serve necessarily to totally disqualify him from

recovery.") (emphasis added). Second, under the analogous

comparative fault doctrine for LHWCA compensation awards, a
____________ ______

stevedore may defend by proving that the longshore worker's

injuries were caused "solely" by his intoxication, cf. 33 U.S.C.
___

903(c). While the longshore worker initially enjoys a rebutta-

ble presumption against such a finding, id. 920(c), the steve-
___

dore's defense is not unprovable. See, e.g., Walker v. Univer-
___ ____ ______ _______

sal Terminal & Stevedoring Corp., 645 F.2d 170, 173 (3d Cir.
__________________________________

1981) (finding 903(c) intoxication defense established, and

noting that the rebuttable presumption "falls out of the case"

once stevedore proffers "substantial evidence" that longshore

worker's intoxication was sole cause of injury or death).

Similarly, in a section 905(b) action, the trial court

may assess the quality of the vessel owner's rebuttal evidence

where the longshore worker failed to demonstrate a vessel "de-

fect"8 and where the vessel owner has proffered "substantial"

____________________

8Given the Scindia standard, evidence of Keller's high
_______
blood-alcohol level cannot be wholly divorced from the threshold
question whether a defective design rendered the Tank 4 ladder
"unreasonably" dangerous. A written policy forbade Simplex
workers from reporting to work intoxicated. Thus, Keller's
blood-alcohol level would be relevant to whether the ladder con-
stituted an "unreasonably" dangerous condition, since the vessel

evidence of the longshore worker's intoxication. Here, the trial

court's consideration of the blood-alcohol level followed direct-

ly upon its observations concerning Keller's failures of proof:

(1) the absence of persuasive expert testimony that the Tank 4
__________ ______ _________

ladder design was so inferior to anticipated safety standards

that the defendant vessel owner could not entrust the equipment

to the stevedore's able charge; and (ii) the absence of evidence

of other accidents on the ladder under substantially similar

conditions. In this context, we interpret these trial court

observations as an acknowledgment not only that Keller utterly

failed to carry his burden of proof but that the only credible
____

evidence of possible causation (i.e., Keller's heavy drinking
____

earlier in the evening and his high blood-alcohol level one hour

after the fall) in no respect implicated the defendant vessel
__ __ _______ __________

owner. See supra note 8.
___ _____

Keller further claims that but for two items of evi-

dence which the district court improperly ignored or excluded, we

would be compelled to conclude that the district court committed

clear error. First, the district court excluded the deposition

testimony of eyewitness Rhonda Rossley, who expressed the opinion

that Keller had hit his head on a railing prior to the fall.

Nonexpert-opinion testimony is permitted only if "(1) rationally

based on the perception of the witness and (2) helpful to a clear


____________________

owner, in turning over the Tank 4 ladder, reasonably could rely
on compliance with the stevedore's policy on intoxication. See

Johnson, 613 F.2d at 348 (trier of fact must consider "the

probability and severity of the harm [the condition] poses").

understanding of the witness' testimony or the determination of

the fact in issue." Fed. R. Evid. 701. See Swajian v. General
___ _______ _______

Motors Corp., 916 F.2d 31, 36 (1st Cir. 1990). The trial court
____________

ruled that the proffered deposition testimony did not meet the

first Rule 701 test because Rossley "did not see [Keller] strike

his head, nor could she see his right hand before he fell[, nor]

observe whether his left hand or his left foot first lost contact

with, respectively, the railing or the ladder rung." Keller, No.
______

81-549-SD, slip op. at 12.

We review a Rule 701 ruling only for manifest abuse of

discretion. See United States v. Paiva, 892 F.2d 148, 156 (1st
___ ______________ _____

Cir. 1989). We find no abuse of discretion. First, Rossley's

opinion necessarily depended upon a forbidden Rule 701 "infer-

ence," because she (i) neither saw Keller strike his head on the

railing, (ii) nor testified to any other sensory perception from
___

which one might rationally infer such an impact (e.g., the sound
____

of impact,a sudden jolt orhalt in Keller's upwardprogress, a pre-

or post-impact cry, or any outward appearance of a head wound or

bleeding).9 Cf. Swajian, 916 F.2d at 36 (finding clear abuse of
___ _______

discretion in allowing lay opinion that wheel fell off rear axle

before car flipped over, based exclusively on the witness's
______

observation that he first saw wheel crossing the road while the

____________________

9Although a medical doctor testified that Keller sustained
an eye injury which could have been consistent with the Rossley
inference, given that Keller also suffered head trauma when he
landed head-first on the tank floor sixteen feet below the 'tween
deck the doctor could not testify that such an inference was
compelled.

32
32














flip-over was in progress). Although Keller's failure to call

out or to try to regain hold of the ladder could be consistent

with sudden disorientation or even unconsciousness, as a lay

witness Rossley would have had no nonspeculative basis for

excluding possible causes other than a blow to the head (e.g.,
____

intoxication, fatigue and heavy exertion).

Second, and perhaps more importantly, this was a bench
_____

trial, in which the trial judge would not only determine the
_____

admissibility of the evidence but serve as the ultimate trier of

fact. The Rule 701 admissibility determination turns on whether

the inference drawn by the nonexpert lay witness would be "help-
_____

ful to . . . the determination of the fact in issue." Thus,
___

having considered the entire proffer, the trial judge excluded
______ _______

the Rossley opinion testimony because the court found no suffi-

ciently reliable basis for the speculative inference on which it

was based. Not only do we agree, but nothing would have required
________

the trial judge, as trier of fact, to credit the Rossley opinion

had it been admitted in evidence, especially since she possessed

no particular skill or experience which would have assisted the

trial court's fact-finding insight. Cf., e.g., Soden v. Freight-
___ ____ _____ ________

liner Corp., 714 F.2d 498, 512 (5th Cir. 1983) (nonexpert witness
___________

with eighteen years' experience repairing trucks can give lay

Finally, Keller contests the exclusion of evidence that

Simplex cut out the two railings on the Tank 4 ladder one day

after the accident, as proof that the original ladder design con-

that this evidence was admissible notwithstanding Rule 407, which

requires the exclusion of subsequent remedial repairs by the

defendant only, not by nondefendants like Simplex. See Raymond

At best, subsequent remedial measures are considered

marginally probative of prior negligence. See John H. Wigmore,

Evidence 283, at 174-75 (1979). In this case, moreover, defen-
________

dant could have capitalized on the very same evidence to demon-

strate that Simplex was expected to make such structural altera-

tions to the HUDDELL without first consulting defendant, and that

defendant was entitled to rely on Simplex, as a reasonably com-

petent stevedore, to take such preemptive measures provided

Simplex deemed them necessary for its employees' safety. See

determining that "a custom-generated duty to supervise and

inspect does not transfer to the ship owner a duty to eradicate

dangers reasonably known to and managed by the stevedore."

Keller, No. 81-549-SD, slip op. at 14 (citing La Martina v. Pan
______ ___________ ___

Ocean Shipping Co., Ltd., 815 F. Supp. 878, 880-81 (D. Md.
__________________________

1993)).

A vessel owner's duty of care normally ceases once it

has discharged its "turnover" duties and the stevedore-employer's

cargo operations have begun. Nonetheless, the Supreme Court has

suggested three settings in which an owner might remain under
_____

some "continuing" duty to monitor, supervise, or inspect the

vessel for hazards developing after stevedoring operations
__________

commence. First, the vessel owner might remain under such a duty

were it to retain actual physical control or custody of a portion

of the vessel, or participate in stevedoring operations. Scin-
_____

dia, 451 U.S. at 167. Keller concedes that these conditions were
___

not met. Second, a duty to intervene might attach in the event

the vessel owner were to acquire actual knowledge that "unsafe
______ _________

conditions" had developed in the vessel's appurtenances since
_________

turnover, that the stevedore-employer will not address the unsafe

condition, and that the stevedore's decision not to remedy the
___

developing hazard was "obviously improvident" in the circum-

stances. Id. at 174-75. Third, even absent actual control,
___

participation or knowledge, a post-"turnover" duty may arise if

the vessel owner was obligated, by contract, statute or custom,




36
36














to monitor stevedoring operations for the purpose of detecting

and remedying unsafe conditions. Id. at 172.
___

Keller's "continuing duty" claim was founded on the

contention that the defendant vessel owner had either actual or

constructive knowledge of an unreasonably dangerous condition

during cable loading operations. However, he does not suggest
______

that the basic structure or design of the Tank 4 ladder changed
_________ ______ _______

after cable loading began (e.g., ladder rungs displaced, loosened
____

or fractured). Therefore, the defendant could have breached no

continuing duty of care to Keller, since the district court
__________

supportably found that the Tank 4 ladder configuration created no

"unreasonable" hazard ab initio. See Scindia, 451 U.S. at 172
__ ______ ___ _______

("We are of the view that . . . the shipowner has no general duty

by way of supervision or inspection to exercise reasonable care

to discover dangerous conditions that develop [i.e., a malfunc-
_______

tioning winch] within the confines of the cargo operations that

are assigned to the stevedore."); Martinez, 903 F.2d at 611
________

("[T]he alleged unsafe condition [employees working on "unsafe"

platform] did not develop during cargo operations; it was either

safe or unsafe at the time the cargo operations began . . . .");

Pluyer v. Mitsui O. S. K. Lines, Ltd., 664 F.2d 1243, 1246 (5th
______ ____________________________

Cir. 1982) (noting "different situation" than in Scindia where
_______

the "case involves the vessel's liability for hazards that

antedate or are coincident with the commencement of cargo opera-
________

tions").

Keller intimates that the relevant "change" or "devel-

opment" which would have been discovered had defendant met its

alleged continuing duty to monitor and intervene was the failure

of Simplex cable loaders to use the Tank 4 ladder in the intended

manner. Thus, Keller would interpret the district court ruling

that "a custom-generated duty to supervise and inspect does

not transfer to the ship owner a duty to eradicate dangers

reasonably known to and managed by the stevedore" as holding

that a vessel owner can never be duty-bound to intervene once an
_____

on-board danger (the risk that longshore workers might resort to

the "over" and "between" methods of egress) becomes "obvious" to

the stevedore.

We cannot subscribe to Keller's reasoning. First, as

already noted, we discern no indication that the trial court

credited evidence that the two alternate methods of exiting Tank

4 were not reasonably safe. Second, even if the district court

had found these other methods of egress "unsafe," initially the
_________

vessel owner could rely on Simplex to manage such "obvious"

defects, unless and until it appeared that Simplex's decision not

to take remedial measures (warnings or railing removal) was

"obviously improvident" under the circumstances. Keller conced-

ed, however, that Simplex, which plainly had actual or construc-

tive notice as to how its longshore workers were exiting Tank 4,

never received an employee complaint about the Tank 4 ladder and
_____

that no accident ever occurred on the ladder either before or
__ ____

after the Keller incident. Thus, evidence presented by Keller


38
38














did not begin to establish defendant's actual knowledge of the

alleged "hazard" on the part of the defendant vessel owner, let

alone any obvious improvidence on the part of Simplex. For the

same reason, even if the defendant vessel owner had been under a

contractual or custom-generated duty to monitor and intervene,

Keller failed to establish a breach.11

CONCLUSION
CONCLUSION
__________


Given the exacting standards of care incumbent upon a

stevedore under the LHWCA, and the supportable trial court find-

ings, we are left with nothing approaching a "definite and firm

conviction that a mistake has been committed." Holmes Transp.,
_______________

Inc., 983 F.2d at 1129. Once the trier of fact determined that
____

the Tank 4 ladder was "safe," its design compatible with "appli-

cable" maritime safety standards, and any potential hazards

sufficiently "obvious" to Simplex longshore workers, it followed


____________________

11Keller argues that the contract between defendant and
Simplex unambiguously provided that defendant, not Simplex, would
___ _______
bear primary responsibility for ongoing "safety" inspections and
_______
modifications to the HUDDELL's work areas following turnover.
Keller points to a contract provision barring Simplex from making
unilateral structural alterations to the HUDDELL. From this
__________
premise, he contends that Simplex was compelled to use the Tank 4
ladder in existence at turnover. We do not agree. First,
contrary to the trial court's alternate finding, this argument
presumes that the ladder was "unsafe." Second, the contract
contemplated that Simplex would bear the primary role in deter-
_______ _______
mining whether modifications were needed, even if defendant was
to be consulted before "major" modifications were undertaken. In
any event, this contention falls far short of demonstrating a
contractual duty on the part of the vessel owner to monitor in
_______
the first instance.
_____ ________

inexorably that the vessel owner was entitled to rely on Simplex,

as an "expert and experienced" stevedore, to act with reasonable

care in supervising its workers in their interaction with and

avoidance of any such "obvious" hazards on board the vessel

during cargo loading operations. Any relevant "hazard" could

have been averted by Simplex in various ways, including the

permanent removal of the safety railings at the top of the Tank 4

ladder, a warning on the ladder as to safe methods of egress, or

simple instruction of its longshore workers.
