          Appeal from the United States District Court
              for the Western District of Louisiana
                           (93-CV-673)

                        February 13, 1997



Before REYNALDO G. GARZA, HIGGINBOTHAM, and DeMOSS, Circuit Judges.
PER CURIAM:*



       This admiralty case involves a slip-and-fall injury aboard a

vessel. Charles Palombo, a vice president of marketing for Red Fox

Companies of New Iberia, La., fell as he attempted to step through

a doorway aboard the M/V David McCall III and suffered certain

injuries.    The cause of the fall is not clear.                  Palombo maintains

that the defendants were negligent in the design and maintenance of

the deck of the vessel’s galley thereby causing Palombo’s fall and

consequent injuries.      He and his wife sued in federal district

court seeking recovery of lost earnings, medical expenses, and

other damages based on their suffering.

       The case was tried to the bench over three days in January,

1996. The district court found that Palombo had not shown any

condition   at   the   threshold    of       the    galley   to    be   unreasonably

dangerous and had failed to prove, first, the existence of a mat at

the   doorway,   and   second,     that       any    such    mat    was   defective.

Accordingly, the court entered judgment for the defendants.                      The

Palombos and Aetna Casualty and Surety Co., as intervenor, appeal.

       The case, asserting personal injuries suffered upon a vessel


      *
      Local Rule 47.5 provides: "The publication of opinions that
merely decide particular cases on the basis of well-settled
principles of law imposes needless expense on the public and
burdens on the legal profession." Pursuant to this Rule, we have
determined that this opinion should not be published and is not
precedent except under the limited circumstances set forth in Local
Rule 47.5.4.

                                         2
in navigable waters, is governed by the negligence law established

under the maritime jurisprudence of the federal courts.              This law

is    informed   by   general   principles   of    negligence    law.      S.C.

Loveland, Inc. v. East West Towing, 608 F.2d 160, 165 (5th Cir.

1979).     The owner of a vessel has a duty to exercise reasonable

care under the circumstances to ensure that those aboard are not

injured.    A plaintiff must prove that something aboard the vessel

created an unreasonable risk of injury, the vessel owner knew or

should have known of this danger, and that the owner failed to

eliminate the danger, and that this danger caused plaintiff’s

injuries.



Standard of Review

       There are two issues in this case: 1) whether the design of

the doorway created an unreasonably dangerous condition, and 2)

whether there was a defective mat in front of the doorway that

caused the accident. The district court found that the doorway was

not    unreasonably    dangerous   and   that     there   was   no   mat   and,

alternatively, if there was such a mat it was not defective.               These

are both findings of fact which we review for clear error.              Ober v.

Penrod Drilling Co., 726 F.2d 1035 (5th Cir. 1984) (Rule 52(a)

applies to bench trials conducted under the general maritime law).

A finding is “clearly erroneous” when although there is evidence to

support it, our review of the evidence leaves us with the “definite


                                     3
and firm conviction that a mistake was committed.”           United States

v. United States Gypsum Co., 333 U.S. 364, 395 (1948).

      We disagree with the appellants’ claim that we should exercise

de novo review of the facts in this case.             They cite Movible

Offshore v. M/V Wilken A. Falgout, 471 F.2d 268 (5th Cir. 1973),

for   the   proposition   that   factual   findings   that   are   unclear,

conclusory, or contradictory are subject to de novo review.            This

is incorrect.    The cited case does not support this assertion and

could not, given that Rule 52(a) does not permit exceptions from

the clearly erroneous standard.       We held in Movible Offshore that

such defective findings might be clearly erroneous, but we did not

stray from our traditionally deferential review posture. Likewise,

the cited case of Hydrospace-Challenger v. Tracor/MAS, Inc., 520

F.2d 1030 (5th Cir. 1975), does not support de novo review, as the

we remanded the case for more findings, all the while mindful of

our deferential role.       Accord Thermo Elec. Corp. v. Schiavone

Constr. Co., 915 F.2d 770 (1st Cir. 1990) (likewise ordering remand

and not suggesting anything about discarding Rule 52(a) standard).

Whether the district court’s determinations here were “clearly

erroneous” is discussed below.



Claim of an Unreasonably Dangerous Condition

      The appellants state that the district court failed to resolve

the question of whether the design of the door created a dangerous

                                     4
condition    requiring    the     presence     of    some   anti-slip     device:

“Although   it   summarized       the   testimony     in    glorious    narrative

fashion, the court below did not delineate how it resolved the

issue!” Appellant’s brief at 13.            Our reading of the lower court’s

opinion leads us to disagree. The court clearly credited Borison’s

opinion and the testimony of various witnesses establishing the

absence of any previous accidents in reaching its conclusion that

there was no unreasonably dangerous condition.               Opinion at 21-22.

As we stated in Movible Offshore, in situations involving ambiguous

findings we may refer to the court’s opinion to help interpret its

findings.   471 F.2d at 272 (citing American Propeller & Mfg. Co. v.

United States, 300 U.S. 475, 479-80 (1937)).

     Palombo     also    claims     that    the     uncontradicted      testimony

demonstrated that the unusual design of the threshold mandated the

use of some sort of anti-slip device.             This is not, however, a fair

summation of the evidence.        Defendants’ expert Borison stated that

the design was not unreasonably dangerous and did not require any

sort of special safety measures:

     Q:     Is there any safety problem at all in your opinion with
            just having a plain no-wax linoleum floor at the entrance
            of a water tight door going into the galley on the David
            McCall III?

     A:     No sir, none at all.

Rec. Vol. VII, pg. 530.       That the district court chose to believe

Borison’s testimony over that of Palombo’s witnesses does not

mandate a finding that the lower court was incorrect.                  The judging

                                        5
of witness credibility is a matter peculiarly within the province

of the trial court and is deserving of the highest degree of

deference on appeal.       E.g., Anderson v. City of Bessemer City, 470

U.S. 564, 575 (1985).       Palombo has given us no reason to find any

error with the court’s choice here.



Claim of Defective Mat

       The   district    court   found   that   there    was   no   mat   at   the

threshold.     If there was such a mat, it found that it was not

defective.     The appellants challenge this finding by stating that

this   finding   is     facially   contradictory    and    therefore      clearly

erroneous.     If the court had stated “there is no mat and it is not

defective,” we would be inclined to agree.              This is not, however,

what it did.       The court obviously credited witness testimony

establishing the nonexistence of the mat.          However, the court went

further and essentially stated that even if there was a mat, it was

persuaded by the witness testimony that stated that this mat was

not defective.        The court’s findings are not contradictory.              In

fact, such alternative findings can often be helpful as they can

obviate the need for a remand for further fact finding when the

evidentiary basis for a fact is found to be insufficient on appeal.

       As stated above, a district court’s credibility choices are to

be disturbed in only the rarest of situations and this is not one

of them.     Further, the appellants have failed to provide us with


                                         6
any legal authority for their conclusion that findings in the

alternative are automatically “clearly erroneous.”   We therefore

find no error with the court’s findings on this issue.



     In sum, we are not persuaded that the lower court’s findings

are clearly erroneous.   We accordingly affirm the lower court’s

judgment for the defendants.

                                                         AFFIRMED.
