Before PHILLIPS, LUCERO, and CARSON, Circuit Judges.
_________________________________
Nicole Wells suffered severe internal abdominal injuries from an underwater
stream of high-pressured water emitted from a Kawasaki personal watercraft (“PWC”)
(commonly called a jet ski1) after she fell backwards off the PWC during acceleration. In
her ensuing lawsuit, she argues that the PWC seat was defectively designed and that
Kawasaki Motors Corp., U.S.A. and Kawasaki Heavy Industries, Ltd. (collectively,
“Kawasaki”) were negligent in relying on warnings to prevent these injuries. She

designated Dr. Anand Kasbekar2 as her expert on the alleged design defects and Ms.
Joellen Gill as her expert on the warnings’ ineffectiveness. Kawasaki moved to exclude
the proposed testimony of both experts. The district court granted the motions,
concluding that both experts’ opinions were unreliable and that Ms. Gill further lacked
the qualifications to give her proposed opinions. Wells appeals from this order as well as
a later one granting Kawasaki summary judgment. We affirm.
BACKGROUND
I. Factual Background
A. The Fall and the Injuries
In summer 2015, sixteen-year-old Nicole Rider (now Nicole Wells) was
vacationing with family members and others at Lake Powell, a reservoir occupying many
square miles in Utah and Arizona. The vacationers had rented Kawasaki 2013-model
PWCs, and while riding as a passenger, Wells fell backward off one. The parties dispute
what happened. Wells contends that she sat down on the PWC’s rear end in the passenger
seat, held on tightly, and slid backward and fell into the water when the driver accelerated
from a stop. Kawasaki disputes that Wells was either sitting or holding on.
Soon afterward, Wells sought treatment from a nearby hospital for sharp lower
abdominal pain. She learned that the pain was from “shocking” internal injuries,

included a ten-centimeter tear at the end of her large intestine, caused by the PWC’s
emitted jet of water, which had “shot [water] up” her rectum,3 Appellant’s App. vol. VIII
at 1715. As part of her injuries, Wells had a significant amount of feces and air injected
into her abdominal cavity. She endured a colostomy to divert fecal material from the
large intestine “into a bag or pouch attached to the abdomen.” Colostomy, John Hopkins
Med., https://www.hopkinsmedicine.org/health/treatment-tests-and-
therapies/colostomy (last visited Mar. 5, 2021). Otherwise, the fecal matter would have
contaminated the areas needing to be healed.
B. Kawasaki’s Warnings
For decades, PWC manufacturers have known that PWC riders are at risk for these
sorts of injuries. Since 2001, they have warned of this risk and others, in a large,
standardized on-product label, which was developed with input from several
stakeholders, including the United States Coast Guard. This label was located on the back
of Kawasaki’s 2013 PWCs and was a critical component of Kawasaki’s warning system.
The label has a bright-orange, bolded heading: “WARNING.” Response Br. of Appellees
at 9 (citing Appellant’s App. vol. X at 2305). Below this warning heading comes this:
WEAR PROTECTIVE CLOTHING: Severe internal injuries can occur if
water is forced into body cavities as a result of falling into water or being
near jet thrust nozzle. Normal swimwear does not adequately protect against
forceful water entry into rectum or vagina. All riders must wear a wet suit
3
When PWC jets are directed at pelvic cavities (i.e., the vagina or the rectum),
the jets can cause “severe physical trauma, sometimes with permanent damage to
sensitive internal tissues and/or organs.” Appellant’s Opening Br. at 3 (quoting
Appellant’s App. vol. XVI at 3917). Researchers have suggested that the risk of these
injuries is greater for passengers, who are, among other things, not supplied with engine-
shutoff lanyards like drivers are.

bottom or clothing that provides equivalent protection (see Owner’s
Manual).
Id. at 9–10 (quoting Appellant’s App. vol. X at 2305). The label contains an infographic
(shown below) depicting a PWC rider wearing a wet-suit bottom, with a caption
identifying it. Id. at 9.
Kawasaki also provided the protective-clothing warning in an instructional video,
and in its owner’s manual. The manual warns in even more detail, adding, for instance,
that “[w]et suits are made of a thick material (neoprene) that significantly retards the
velocity of water passing through it” and that “[n]ormal swim wear will not adequately
protect you.” Appellant’s App. vol. IX at 2144. Despite the warnings, Wells was riding
the PWC in an ordinary bathing suit.
C. Kawasaki’s PWC Seats
Key to Wells’s case is that for 2013 PWCs, Kawasaki produced two seat
options—a standard seat and a luxury (“LX”) seat, which provided more hip support. The
model Wells was riding offered only the standard seat. Kawasaki maintains that the LX
seat was a comfort, not a safety, feature.
4
II. Procedural Background
Wells sued Kawasaki for causing her abdominal injuries.4 She alleges negligent
and strict-liability design defects, arguing that “a redesigned seat” (with a hip support like
that on the LX seat) “was feasible and would reduce the risk of [orifice injuries] by
making it less likely that a passenger would slide off the rear of the PWC and into the
path of the jet thrust.” Appellant’s Opening Br. at 5. In addition, she contends that “it was
negligent [for Kawasaki] to rely on warnings to protect passengers from this risk, since
manufacturers knew or should have known that warnings were completely ineffective in
changing the behavior of PWC users.”5 Id. She relied on Dr. Kasbekar as the expert for
the first theory and Ms. Gill for the second.
Kawasaki moved to exclude the proffered expert testimony of both Dr. Kasbekar
and Ms. Gill, and then sought summary judgment based on Wells’s inability to show a
dispute of material fact without these experts’ testimony. The district court granted all of
Kawasaki’s motions. It reasoned that both proposed expert opinions were unreliable and
that Ms. Gill was also unqualified to assert her proposed opinions. Then the court granted
summary judgment for Kawasaki, ruling that “[a]bsent expert testimony, Plaintiffs’
design defect and failure to warn claims fail.” Appellant’s App. vol. I at 0282. Wells

Wells also sued the PWC rental company but these claims have since settled.

Kawasaki argues that the Complaint does not allege this theory. We do not
address this issue because we affirm on other grounds. See Rimbert v. Eli Lilly & Co.,
647 F.3d 1247, 1256 (10th Cir. 2011) (“[T]his court may affirm on any ground
apparent in the record.” (citations omitted)).
Wells had also claimed breach of warranty but in her opposition to summary
judgment, she conceded to dismissing this.

timely filed this appeal challenging all three decisions. We review, exercising jurisdiction
under 28 U.S.C. §§ 1291 and 1332–33.
DISCUSSION
Wells contests the exclusion of her experts’ testimony and the associated grant of
summary judgment for Kawasaki. We first address the exclusion of Dr. Kasbekar’s
expert opinion; then Ms. Gill’s; and last, the propriety of granting summary judgment.
I. Exclusion of Expert Testimony
“We review de novo ‘whether the district court employed the proper legal standard
and performed its gatekeeper role’ in determining whether to admit or exclude expert
testimony.” United States v. Nacchio, 555 F.3d 1234, 1241 (10th Cir. 2009) (quoting
United States v. Rodriguez–Felix, 450 F.3d 1117, 1122 (10th Cir. 2006)). “We review for
abuse of discretion the manner in which the district court performs this gatekeeping role.”
Id. (citing Dodge v. Cotter Corp., 328 F.3d 1212, 1223 (10th Cir. 2003)). Under this
standard, we do “not disturb the district court’s ruling unless it is ‘arbitrary, capricious,
whimsical or manifestly unreasonable’ or when we are convinced that the district court
‘made a clear error of judgment or exceeded the bounds of permissible choice in the
circumstances.’” Dodge, 328 F.3d at 1223 (quoting Atl. Richfield Co. v. Farm Credit
Bank of Wichita, 226 F.3d 1138, 1163–64 (10th Cir. 2000)).
Rule 702 of the Federal Rules of Evidence permits expert testimony when the
witness “is qualified as an expert by knowledge, skill, experience, training, or education”
and four factors are met: (1) “the expert’s scientific, technical, or other specialized
knowledge will help the trier of fact to understand the evidence or to determine a fact in
6
issue”; (2) “the testimony is based on sufficient facts or data”; (3) “the testimony is the
product of reliable principles and methods”; and (4) “the expert has reliably applied the
principles and methods to the facts of the case.”
The reliability prong “requires the court to determine whether the expert’s
opinions are supported by sound reasoning and methodology.” Delsa Brooke Sanderson
v. Wyo. Highway Patrol, 976 F.3d 1164, 1172 (10th Cir. 2020) (citing F & H Coatings,
LLC v. Acosta, 900 F.3d 1214, 1222 (10th Cir. 2018)). Expert testimony must have “a
reliable basis in the knowledge and experience of [the relevant] discipline,” Dodge, 328
F.3d at 1221–22 (alteration in original) (quoting Kumho Tire Co. v. Carmichael, 526 U.S.
137, 149 (1999)), and be based “on actual knowledge, not ‘subjective belief or
unsupported speculation,’” id. at 1222 (quoting Daubert v. Merrell Dow Pharms., Inc.,
509 U.S. 579, 590 (1993)). In Daubert, the Supreme Court listed four non-exclusive
factors to consider when assessing reliability, which we have summarized as this:
(1) [W]hether the opinion at issue is susceptible to testing and has been
subjected to such testing; (2) whether the opinion has been subjected to peer
review; (3) whether there is a known or potential rate of error associated with
the methodology used and whether there are standards controlling the
technique’s operation; and (4) whether the theory has been accepted in the
[relevant] community.
Id. (citing Daubert, 509 U.S. at 593–94). As noted, “the test of reliability is ‘flexible,’
and Daubert’s list of specific factors neither necessarily nor exclusively applies to all
experts or in every case.” Kumho Tire Co., 526 U.S. at 141.
The relevance prong of Rule 702 “encompasses [the rule]’s requirement that the
evidence ‘[help] the trier of fact to understand the evidence or to determine a fact in
7
issue.’” Delsa Brooke Sanderson, 976 F.3d at 1172 (second alteration in original)
(quoting Daubert, 509 U.S. at 591). “In essence, the question is ‘whether [the] reasoning
or methodology properly can be applied to the facts in issue.’” Rodriguez–Felix, 450 F.3d
at 1123 (alteration in original) (quoting Daubert, 509 U.S. at 593).
A. Exclusion of Dr. Kasbekar’s Proposed Expert-Opinion Testimony
Wells first challenges the exclusion of Dr. Kasbekar’s proffered opinion that Wells
would have been less likely to fall had Kawasaki equipped her PWC with the LX seat. To
reach this conclusion, Dr. Kasbekar employed a drag test he had designed. For this, he
weighted a bag to Wells’s summer-2015 weight, covered it in bathing-suit material to
replicate what Wells had been wearing and placed the bag on a PWC seat. Then, he used
a cable-and-pulley system to measure the force needed to slide the bag from the seat.
After three tests of each seat, he used basic physics formulas to calculate the acceleration
needed to produce this force. Based on this, Dr. Kasbekar opined that Wells would have
slid on the standard seat within the acceleration capacity of the PWC, but that she would
not have slid (and thus fallen) had she instead sat on the LX seat.
The district court ruled that this seat-testing method was unreliable, after noting
that it had not been subjected to peer review and had no known rate of error. The court
ruled that Dr. Kasbekar’s deposition testimony alone could not establish that the method
was reliable.
Even if we believed that Dr. Kasbekar’s method was reliable, that would not
suffice to show that the district court abused its discretion in concluding otherwise. Cf.
Dodge, 328 F.3d at 1223 (describing an abuse of discretion as a decision that is
8
“arbitrary, capricious, whimsical or manifestly unreasonable”; “a clear error of
judgment”; or beyond “the bounds of permissible choice in the circumstances” (quoting
Atl. Richfield Co., 226 F.3d at 1163–64)). No peer-reviewed literature supports that this
method should be used to test seat design and the rate of error is unknown. The district
court need not have found Dr. Kasbekar’s proposed expert opinion reliable based only on
his testimony. Cf. Gen. Elec. Co. v. Joiner, 522 U.S. 136, 146 (1997) (“[N]othing in
either Daubert or the Federal Rules of Evidence requires a district court to admit opinion
evidence that is connected to existing data only by the ipse dixit of the expert.”).6
B. Exclusion of Ms. Gill’s Proposed Expert-Opinion Testimony
Next, Wells challenges the exclusion of Ms. Gill’s proposed opinion concerning
Kawasaki’s warnings. Wells offered this expert testimony to support her claim that “it
was negligent to rely only on warnings to protect passengers from [the risk of orifice
injuries], since manufacturers knew or should have known that warnings were completely
ineffective in changing the behavior of PWC users.” Appellant’s Opening Br. at 5. First,
Wells contends that the district court failed in its gatekeeping role by not examining the
6
Wells suggests that Dr. Kasbekar’s test results were consistent with what is
shown in two items of evidence Kawasaki produced: (1) a video which, according to
Dr. Kasbekar, shows that PWC passengers slide backward during acceleration, and
(2) computer simulations replicating passenger falls from PWCs. But Wells misses
the mark because neither of these show that a passenger is less likely to slide
backward off a PWC when it has an LX seat, as Dr. Kasbekar proposes opining.
As additional support for Dr. Kasbekar’s opinion, Wells offers this quotation
from his expert report: “Kawasaki’s own 2013 marketing information related to the
alternative seat design . . . indicates that ‘Thanks to its well engineered seat steps riders
feel much more connected to the watercraft under hard acceleration.’” Appellant’s App.
vol. XV at 3656. But marketing information is merely puffery and this marketing does
not establish that the LX seat would likely have prevented Wells’s injuries.
9
admissibility of Ms. Gill’s ultimate “primary opinion.” Id. at 23, 26. By this, she means
that given the nature of the risk, “the decision to rely on warnings to protect users from
this hazard was a violation of established safety principles.” Id. at 25. She faults
Kawasaki for not seeking a design solution. See id. at 26 (“There are some cases where a
warning is not the appropriate solution. There has to be a design solution.”); Appellant’s
Reply Br. at 9 (“Taken together, Ms. Gill’s opinion was that the decision to rely on
warnings to protect users from the risk of orifice injury was the Kawasaki Defendants’
main violation”); Appellant’s App. vol. I at 0173 (“Fundamentally, Ms. Gill is of the
opinion that (1) Defendants’ warnings on the [PWC] were insufficient to keep Ms. Wells
reasonably safe from harm, and (2) the manner in which people typically use and
experience the [PWC] render warnings of any kind ineffective in mitigating the danger
posed by the device.”).
The district court described Ms. Gill’s proposed opinion as follows:
[Kawasaki] should have known that its warnings and instructions were
defective and likely to be ineffective because
a. Many riders would not see or read the Owner’s Manual and
Operating Instructions;
b. Users would not find and choose to read the on-product label
that warns of the subject hazard because of its location, its
lengthiness/excessive verbiage, and because it contains information
that is in contradiction to what is commonly observed and so forth—
leading to [Ms.] Gill’s conclusion that the label would not likely
motivate users to wear protective clothing; and
c. The on-product label warning . . . is ambiguous as to the
meaning of equivalent protection.
10
Appellant’s App. vol. I at 0274 (citations, internal quotation marks, and footnote
omitted).
Even if the district court somehow failed in its gatekeeper obligation, and if Wells
in fact preserved this issue for appeal, we would conclude that the district court did not
abuse its discretion in excluding Ms. Gill’s primary opinion. See Rimbert v. Eli Lilly &
Co., 647 F.3d 1247, 1256 (10th Cir. 2011) (“[T]his court may affirm on any ground
apparent in the record.” (citations omitted)). This is so because the opinion is
unreliable. First, it is based in part on the opinion that Kawasaki’s warnings were
deficient and ineffective, but as explained below, the court acted within its discretion
in rejecting that view. Second, this primary opinion presupposes that an alternative
design existed, but no data supports this assumption. Cf. Yonts v. Easton Technical
Prods., Inc., 676 F. App’x 413, 418 (6th Cir. 2017) (“It is misleading to put so much
weight on potential design alternatives when there is no evidence that feasible
alternatives exist and minimal evidence that [the company] has not pursued any.”).
Dr. Kasbekar’s proposed testimony on an alternative design is inadmissible, and Ms.
Gill has not examined other design solutions and offers no opinion on this topic.7
Next, Wells argues that the district court erred in finding that Ms. Gill lacked
qualifications for that part of her opinion the court did address and in finding that this was
unreliable. We do not address Ms. Gill’s qualifications. Instead, we affirm the court’s
ruling on reliability.
7
Moreover, Ms. Gill stated that she is not a design engineer.
11
The court summarized that the opinion was unreliable for this reason: “Instead of
offering an opinion that has been subjected to the rigors of testing, peer review, and
acceptance throughout a broader community, Plaintiff is proposing that Ms. Gill present
an opinion based on generalized studies of warning labels and a limited subset of
deponents—all without independent testing.” Appellant’s App. vol. I at 0278. Even
though Ms. Gill has relevant experience with warnings and cites some general studies
of warning labels, we discern no abuse of discretion in the district court’s decision to
exclude her testimony because of insufficient factual support. See Bitler v. A.O. Smith
Corp., 400 F.3d 1227, 1233 (10th Cir. 2005) (“[A] plaintiff must show that the
method employed by the expert in reaching the conclusion is scientifically sound and
that the opinion is based on facts which sufficiently satisfy Rule 702’s reliability
requirements.” (quoting Mitchell v. Gencorp Inc., 165 F.3d 778, 781 (10th
Cir.1999)). Ms. Gill cites merely a few deponents’ testimony and one article on PWC
warnings to support her point that consumers would not locate and read the on-product
label, and cites no research or data to support her other points.
II. Summary Judgment
Finally, Wells asks that we reverse the summary judgment order if we reverse the
exclusion of her experts. We review this issue de novo, Schulenberg v. BNSF Ry., 911
F.3d 1276, 1285 (10th Cir. 2018) (citation omitted), and will find for Wells only if she
“shows that there is no genuine dispute as to any material fact and [that she] is entitled to
judgment as a matter of law,” id. (quoting Fed. R. Civ. P. 56(a)). Wells has not argued
that a genuine dispute of material fact exists if Dr. Kasbekar’s and Ms. Gill’s opinions are
12
inadmissible. Because we affirm the rulings that these are inadmissible, we affirm the
order of summary judgment for Kawasaki as well.
CONCLUSION
For the foregoing reasons, we affirm.
