MEMORANDUM**


2
In September 1989, the vessel OMNISEA collided with a pier in the East Duwamish waterway, United States navigable waters near Seattle, Washington.   At that time, Maurice Davis was aboard the OMNISEA as a seaman.   Davis claimed that he sustained a serious head injury as a result of being knocked over by the collision.   Davis sued Unisea, Inc., the vessel owner, under general maritime law for maintenance and cure;  the district court had jurisdiction pursuant to 28 U.S.C. § 1333.


3
While the fact of the collision was undisputed, Unisea claimed that the accident did not cause Davis' symptoms.   Experts for both parties diagnosed Davis as suffering from an organic affective personality disorder, causing sudden, violent behavior.   Davis' expert testified that a closed head injury caused the disorder;  the expert for Unisea testified that the disorder had no relation to the claimed injury.   The sole issue for the district court was the cause of Davis' disorder.   After a two day bench trial, the district judge ruled in favor of Unisea.   Davis timely appeals;  we affirm.1

Fed.R.Civ.P. 52(a)."   Brooker v. Desert Hosp. Corp., 947 F.2d 412, 415 (9th Cir.1991) (quoting  Rozay's Transfer v. Local Freight Drivers, Local 208, 850 F.2d 1321, 1326 (9th Cir.1988), cert. denied, 490 U.S. 1030 (1989)).   Findings of fact that turn on credibility determinations deserve heightened deference due to "the factfinder's unique opportunity to observe the demeanor of the witnesses."   Newton v. National Broadcasting Co., Inc., 930 F.2d 662, 671 (9th Cir.1990) (citation omitted).   Admiralty cases have no special standing in this regard.   Sauers v. Alaska Barge, 600 F.2d 238, 244 (9th Cir.1979) ("In admiralty, as in other types of cases, this court will not overturn the trial court's findings unless we are left with the definite and firm conviction that a mistake has been committed.").

This appeal raises no questions of law.   After reviewing the trial transcripts and the district court's holding, it is clear that the credibility of the witnesses and their testimony comprised the very heart of the ultimate ruling.   It is in this province that an appellate panel is least equipped to proceed.

The district judge stated:

6
[T]here is a profound frustration that the Court feels when trying to deal with a case such as this, where there is a clear fact dispute as to what in fact occurred or whether an injury occurred when the testimony of some of the witnesses could be most charitably described as dissembling....


7
The inconsistencies in the testimony in the plaintiff's case here are so pervasive as to preclude in my mind a finding that the plaintiff has met his burden of proving a causal connection between the vessel accident and his current problems, and I must, therefore, direct the entry of judgment of behalf of the defendant.

Davis' other arguments are meritless.   The decision of the district court is

AFFIRMED.
