Ana Matos brought this action to recover for the death of her husband, Joaquim Matos, who drowned after falling off the F/V Lutador, a commercial fishing vessel owned by defendant Silva Fishing Corporation. Joaquim Matos was a mate aboard the vessel. The captain was Jose Silva, president of Silva Fishing.

Early on the morning of October 10, 1997, Joaquim Matos noticed that some wires attached to the vessel’s trawl doors were tangled. The doors, located in the aft of the vessel, are used to keep the fishing net open while it is dragged through the water. Matos informed Silva, who took over the controls of the vessel and a winch used to operate the doors. With the assistance of Silva and two other crewmembers, Matos was able to untangle the wires, but the starboard-side door got caught on a chain. Matos signaled Silva to raise and lower the doors with the winch, but this effort did not free the door from the chain.

On his own initiative, Matos placed one foot on the railing of the vessel and one foot on the starboard side door, which was partially submerged in the water. Using a hammer he pounded the chain trying to loosen it from the door. Silva, who was at the front of the vessel at the time, yelled at Matos to get off the door and back into the boat because he feared Matos might get hurt, but Matos either did not hear him or simply ignored the order. As Matos was hammering, the door suddenly dropped and he fell into the water.

A crewmember threw an unattached life ring into the water, but it landed 20 feet from Matos and Matos did not try to swim toward it. Silva turned the vessel toward Matos, coming within four feet of him. A deckhand threw Matos another life ring which landed one or two feet from him, but again Matos was unresponsive. Before the deckhand could jump into the water, Matos submerged and disappeared, only seven minutes after he fell off the vessel.

Ana Matos contended at trial that Silva Fishing was negligent under the Jones Act, 46 U.S.C. § 688 (1994), in failing to provide her husband a safe workplace and in failing to conduct a proper rescue operation once he fell overboard and that the vessel was unseaworthy in several respects under general maritime law. In a special verdict, the jury found inter alia that the defendant, Silva Fishing, was not negligent, and that, although the F/V Lutador was unseaworthy, its unseaworthiness was not a proximate cause of Matos’ death. It also found that Matos’ own negligence was a 95 percent cause of his death.

On appeal, Matos challenges the jury instructions that were given and the qualifications of Silva Fishing’s expert. We reject her claims for reasons explained below. Because most of Ana Matos’ arguments parallel those that we recently considered and rejected in Hopkins v. Jordan Marine, Inc., 271 F.3d 1 (1st Cir. 2001), we rely primarily upon our discussion in that case.

Matos first argues that the district court effectively allowed assumption of the risk as a defense when it told the jury that “[a] seaman, when he enters upon his calling, must assume the unavoidable risks of his occupation” and may not recover for “the normal hazards of his business.” It is true that assumption of the risk is not a bar to recovery, either for unseaworthiness or under the Jones Act, *26 see Hopkins, 271 F.3d at 4; but the now disgarded doctrine does not forbid use of the words “assume” or “risk.”

Rather, as Hopkins explains, assumption of the risk was a doctrine that precluded a plaintiff from recovering, even where the owner was shown to be negligent or the ship unseaworthy, because the plaintiff had known of the action or condition and “assumed the risk” by continuing to work. No such instruction was given here. The complained of instruction, read in full, merely said that there was no liability if no one was at fault and the accident was simply one of those normal incidents of life at sea. 1

Matos also complains that the instruction on contributory negligence contained error and that the charge on negligence did not sufficiently stress the extent of the obligation. But the charge on negligence gave the substance of what Matos says should have been included. And given the jury finding that unseaworthiness did not cause the harm (which disposed of one claim) and the finding that there was no negligence (which disposed of the other), the 95 percent allocation of blame to Joaquim Matos was beside the point.

In a final criticism of the instructions, Ana Matos says that the court erred in telling the jury that an act or omission is the cause of an injury or death if the harms would not have happened “but for” the act or omission. The argument is that the jury may have been misled into thinking, wrongly, see Hopkins, 271 F.3d at 4, that the defendant’s act or omission had to be the sole cause. However, the district court twice told the jury explicitly that it was enough if the defendant’s negligence (in one case) or act or omission (in the other) “played any part, no matter how small,” in bringing about the injury. 2

Finally, Ana Matos says that the district judge abused her discretion in allowing Silva Fishing’s expert to testify. The main objection is that although a former Coast Guard officer and long a marine surveyor and accident investigator, the expert had never served in a commercial fishing operation. This is not only the same objection, but also the same expert who testified in Hopkins; and our decision in Hopkins applies equally in this case.

Affirmed.
