Patrick Graham (“Graham”) appealed from the summary judgment granted to the vessel owner and owner pro hac vice in their action for exoneration and limitation of liability. Graham was an adult volunteer and “mate” *863on an outing with the Sea Explorers, a nautical troop of boy scouts. Graham was injured when he dove into shallow water to swim to shore and secure the bowline. The main issue on appeal is whether the district court was correct when it found as a matter of law that Graham was not a seaman under the Jones Act. We find that there is a genuine issue of material fact, making summary adjudication improper, and reverse and remand.***
Graham was a volunteer aboard The Ambrose, on a 10-day training cruise for a small troop of Sea Explorers. The unit for which Graham volunteered chartered a vessel from the Mt. Diablo Boy Scouts of America. Graham had previously been a Sea Explorer himself, and was serving as “mate” to the skipper, William Brazil. Brazil had selected Graham to assist him, and submitted Graham’s application to the Mt. Diablo Council of Boy Scouts for approval. Both the adult volunteers and the children were required to pay annual registration fees and all were charged for expenses incurred during the cruise of The Ambrose. The activities of the voyage included training the children in navigation as well as recreation such as skiing and swimming. Graham and Brazal were the only two adults on board, and both had supervisory authority over the children.
On June 18,1992, the third day of the trip, William Brazil was mooring the vessel off Brannan Island State Park. Brazil was supervising one scout who was at the helm. Graham and another scout had put out the stem anchor. Graham, intending to swim the bowline to shore to secure the boat, dove off the bow of the vessel into approximately three feet of water. He suffered quadriplegic injuries as a result of diving into the shallow water.
Brazil had not given any direct orders to Graham to leave the boat or to take the bowline to shore. There had been a brief meeting before mooring where Brazil determined that the bowline would be secured to an object on shore.
Graham filed a negligence claim against William Brazil in state court. The owner of the vessel, Mt. Diablo, and owner, pro hae vice, Post 248, filed this action for exoneration from or limitation of liability in district court pursuant to Federal Rule of Civil Procedure F. The deadline for filing claims and answers to the complaint, set by the district court, was September 14,1993. On that day Graham filed an answer but made no affirmative claims. On September 17, without asking leave of the district court, Graham filed an amended answer which stated an affirmative claim seeking 10 million dollars in contribution and indemnity. The court allowed this amended answer to be filed. This amended answer alleges The Ambrose was unseaworthy and that the accident occurred because of the negligence of the personnel aboard.
On April 7, 1994, Graham asked for leave to file an amended claim. This amended claim added a claim under the Jones Act, 46 U.S.C.App. § 688, re-alleged that The Ambrose was unseaworthy and improperly manned, and changed the relief sought from contribution and indemnity to maintenance and cure. Appellees opposed the motion to amend and filed separate motions for summary judgment. The district court denied the motion to amend and ordered summary judgment against appellant.
We review grants of summary judgment de novo. Warren v. City of Carlsbad, 58 F.3d 439, 441 (9th Cir.1995). The district court’s denial of a motion to amend is reviewed for abuse of discretion. United States v. County of San Diego, 53 F.3d 965, 969 n. 6 (9th Cir.1995). Such a denial is strictly reviewed in light of the strong policy permitting amendment. Texaco, Inc. v. Ponsoldt, 939 F.2d 794, 798 (9th Cir.1993).
DISCUSSION
Jones Act protection extends to “[a]ny seaman who shall suffer personal injury in the course of his employment____” 46 U.S.C.App. § 688. The Jones Act does not define the term “seaman” and the question *864has been the subject of much litigation. Two recent Supreme Court cases address the question of who is a “seaman.” Chandris, Inc. v. Latsis, — U.S.-,-, 115 S.Ct. 2172, 2193, 132 L.Ed.2d 314 (1995); McDermott Int’l Inc. v. Wilander, 498 U.S. 337, 111 S.Ct. 807, 112 L.Ed.2d 866 (1991).
The test regarding who is a seaman under the Jones Act is a mixed question of law and fact. Wilander, 498 U.S. 337, 111 S.Ct. 807. “If reasonable persons, applying the proper legal standard, could differ as to whether the employee was a ‘member of a crew,’ it is a question for the jury.” Id. at 356, 111 S.Ct. at 818. To qualify as a seaman under the Jones Act the worker must show two basic elements:
the worker’s duties must contribute to the function of the vessel or to the accomplishment of its mission, and the worker must have a connection to a vessel in navigation ... that is substantial in terms of both its duration and nature.
Chandris, — U.S. at-, 115 S.Ct. at 2193. Chandris was decided after the briefing in this case and neither party submitted supplemental authority.
The previous test established in Bullis v. Twentieth Century-Fox Film Corp., 474 F.2d 392 (9th Cir.1973), included the “in aid of navigation” language and is no longer controlling. Under Wilander, the vessel needs to be one “in navigation,” but the duties of the seaman do not need to be “in aid of navigation.” There is no question that The Ambrose was a vessel in navigation.
Graham contributed to the operation of the vessel. The facts show that he was the “mate,” and one of only two adult crew members aboard. Despite the lack of formally assigned duties, Graham was engaged in navigation, and in furthering the mission of the vessel, which was working with the boy scouts on board. He was, in the words of the Supreme Court, “doing the ship’s work.” Wilander, 498 U.S. at 355, 111 S.Ct. at 818.
The issue here is with the second part of the Chandris test and whether Graham’s connection to the vessel was substantial in terms of both its duration and its nature. The Supreme Court has not addressed the issue of a gratuitous worker who is only occasionally at sea. The facts in both Wilander and Chandris involve professional seamen who were paid for full-time work. The disputes in those cases focus on whether the employee was engaged primarily in land based activities or primarily in the operation of the ship in navigable waters.
In this case, Graham was not doing any land-based work. When he was acting as mate of the vessel, he was closely associated with the ship. The cruise only lasted ten days, and Graham was not a professional seaman. The Supreme Court has said that the Jones Act is fundamentally status-based, “granting a cause of action to those maritime workers who form the ship’s company.” Chandris, — U.S. at-, 115 S.Ct. at 2186.
Although Chandris came down after the district court’s order in this ease, the district court relied on similar language: “seaman status is a jury question only if there is evidence that ... the plaintiff was ‘assigned permanently to a vessel____’ ” citing Coats v. Penrod Drilling Corp., 5 F.3d 877, 890 (5th Cir.1993), cert. denied, — U.S. -, 114 S.Ct. 1303, 127 L.Ed.2d 654 (1994) reh’g en banc granted, 20 F.3d 614 (1994), opinion reinstated in part, 61 F.3d 1113 (5th Cir. 1995). The district court in this case concluded that Graham failed to satisfy his burden of showing that he had “more or less permanent status in an employment-related position.” The new test, quoted above, is whether his connection was “substantial in terms of both its duration and nature.” Chandris, — U.S. at-, 115 S.Ct. at 2193.
The district court’s finding relied on the following facts:
(1) Graham was not paid for his services ...; (2) Graham viewed his status on board as that of a “volunteer” ...; (3) Graham was not “hired,” but rather signed up with the Post as a volunteer adult supervisor ...; (4) Graham understood that part of his job on The Ambrose was to supervise and train the youths along with the Skipper, Mr. Brazil, as well as to serve as Brazil’s mate ...; and (5) The Ambrose was not a commercial venture or on a serious training mission, but was engaged in a primarily recreational cruise that in-*865eluded siding, suntanning, and swimming as well as basic, informal nautical instruction for the underage crew of Boy Scouts.
For the reasons set forth below, we find that the district court erred in finding that this factual situation could not lead any reasonable trier of fact to conclude that Graham was a seaman.
The purpose of the Jones Act is to protect maritime workers. It is ordinarily for the trier of fact to determine whether someone who does not work for wages is a maritime worker covered by the Jones Act. Only a few district courts have grappled with the issue of whether a gratuitous worker who is only occasionally at sea can be a seaman for Jones Act purposes.
A district court in Florida found that a person who volunteered to participate in a yacht race for personal pleasure, who was promised no wage or salary, but who was actually performing normal crew service when injured was a seaman under the Jones Act. Petition of Read, 224 F.Supp. 241 (D.C.Fla.1968).
A Rhode Island case involving similar, but not the same, circumstances, Heath v. American Sail Training Ass’n, 644 F.Supp. 1459 (D.R.I.1986) declined to grant seaman status to volunteer crew members. Heath held that no employment relationship existed between the organizer of a sail training program and the crew members, and that the crew members who were unpaid temporary volunteers, could not maintain a Jones Act claim against the organizer. 644 F.Supp. at 1470-71. Although this case is not binding on this Court, it is distinguishable. The Heath court found difficulty in establishing that there was an employer-employee relationship with the program organizer. Id. at 1469. The Heath court found it significant that the volunteers were not engaged for work purposes on ASTA’s behalf; that the volunteers actually paid ASTA for the privilege of participation in the sailing event; that ASTA had no “meaningful power of dismissal over the trainees once the cruise began”; and that the volunteers were given considerable discretion in selecting what they wanted to do on the ship. Id.
However, the court in Heath also noted that “an unpaid temporary crew person may indeed qualify as an employee for Jones Act purposes____” Id. And while the defendants in Heath argued that the crew not being compensated was a determinative factor, the court found this approach to be “too parochial a view.” Id. at 1468. The court went on further to state that “[w]age payment is not a sine qua non for qualification as an employee under the common law.” Id. Finally, the Heath court provided the four elements that it considers in making this type of status determination: (1) the selection and engagement of the putative employee; (2) the situation vis-a-vis payment; (3) the situs of the power of dismissal; and (4) the situs of control over on-the-job conduct. Id. Of the four elements, the court regarded “payment of wages [ ] the least important.” Id. See also Petition of Read, 224 F.Supp. 241 (S.D.Fla.1963).
The factors above were derived from the law of agency. In that context, “[cjonsideration is not necessary to create the relation of principal and agent and it is not necessary in the case of master and servant.” Read at 245, citing Restatement (Second) Agency 225 at 497.
Graham was in a different position fi’om the plaintiffs in Heath because he was at the disposal of Brazil. Not only did Brazil select Graham, and have the power to dismiss, but he also had the authority to control his on-the-job conduct. These controls weigh in favor of establishing an employment status between Graham and Brazil.
Finally, a case that involved the question of “seamen” status Complaint of Falkiner, 716 F.Supp. 895 (E.D.Va.1988) is also distinguishable. In Falkiner, the court found that volunteer cannoneers who were injured aboard a yacht during a mock pirate battle during a festival, were not seamen for Jones Act purposes. 716 F.Supp. at 903. The injured parties submitted for decision the issue of their status as seamen within the purview of the Jones Act. Id. at 901.
The Falkiner court found significant the following: that the FalHners, who were the owners of the vessel on which the claimants were injured, did not select the claimants to *866participate in the mock battle; that the Falkiners did not pay the claimants’ wages; that the claimants and the Falkiners were jointly participating in the event; that the Falkiners never exercised exclusive control over the claimants as cannoneers; and that the claimants were not performing a service normally provided by the crew. Id. at 902.
The Falkiner court concluded that under these circumstances, the claimants were not seamen for Jones Act purposes. Again, the compensation factor was only one of several factors that the court weighed and was by no means the sole or even the predominant consideration.
In Falkiner, the court relied heavily on the fact that the cannoneers were not “performing some type of work typically performed by the [vessel’s] crew.” Id. at 904. In the case at hand, Graham was at all times performing “typical” crew work, including assisting the skipper as his mate.
The duration of time aboard a vessel is not enough, standing alone, to determine status as a seaman under the Jones Act. The Supreme Court has expressly rejected what it referred to as the “voyage” test, that is that anyone working on board a vessel for the duration of a “voyage” in furtherance of the vessel’s mission has the necessary employment-related connection to qualify as a seaman. Chandris, — U.S. at---, 115 S.Ct. at 2184-85. Instead the court has endorsed a “status-based” standard stressing that the seaman status belongs to “those maritime workers who form the ship’s company.” Id. at ——, 115 S.Ct. at 2186.
Thus, under the circumstances, there is a genuine issue .of material fact as to whether Graham had a connection to The Ambrose that was substantial in duration and nature.
Motion for Leave to Amend
The district court denied Graham’s motion for leave to amend finding that the amendment would be futile. The proposed amendment was offered six months after the first amendment to his answer, and added the Jones Act claim. The district court found that “absent evidence that Graham was working aboard The Ambrose in a more or less permanent status in an employment-related position, he cannot maintain an action under the Jones Act.” Because we find that there is a question of fact regarding Graham’s seaman status that could not be decided by summary adjudication, we also find that the district court erred in denying Graham’s motion to amend his answer on the ground that it was futile.
Reversed and remanded for further consideration consistent with this opinion.
Appellant previously conceded that summary judgment was appropriate in favor of Mount Diablo Silverado Council. Therefore, we clarify that this opinion AFFIRMS as to Appellee Mount Diablo Silverado Council, and REVERSES only as to Explorer/Sea Scout Post 248.
