The Dauphin Island Bridge crosses the Gulf Intracoastal Waterway, which runs east to west, in Mobile County, Alabama. As found by the district court, the “project channel” in the vicinity of the bridge has a width of approximately 150 feet and runs roughly down the middle of the Waterway. It is subsumed within the Waterway’s “navigable channel.” The navigable channel, approximately 350 feet wide (including the width of the project channel), is bounded on the north by a line of red buoys and on the south by a series of black buoys. The Army Corps of Engineers is generally responsible for maintaining the navigability of the project channel. In areas of the Waterway outside the project channel, the Corps is responsible for removing only those hazards to navigation known to them.
The bridge incurred extensive damage when Hurricane Frederick hit the Mobile area on September 13, 1979. After the hurricane, the Coast Guard closed the Waterway in the vicinity of the bridge and the Corps surveyed the project channel for obstructions to navigation. The Corps did not survey the area of the Waterway outside the project channel. The Coast Guard replaced in their original positions the buoys that were missing as a result of the hurricane and reopened the Waterway.
By permit dated January 3, 1980, the Coast Guard authorized the State of Alabama to replace the bridge. The plans for the new bridge called for the widening of the bridge’s fender system, which was intended to protect the bridge from allisions with vessels navigating through the bridge. The horizontal clearance between the north and south fenders of the old bridge was 180 feet and included the width of the project channel. The clearance of the new bridge was to be 350 feet, but the project width was to remain at 150 feet. Alabama contracted with Meisner Marine Construction Company to demolish the old bridge and Brown & Root, Inc. to build the new one.
Meisner began work in February 1980, using explosives with the knowledge of the Coast Guard. In March, after the removal by Meisner of the fenders and the main concrete support piers behind the fenders, the Coast Guard placed four new, tempo *1063 rary buoys, two immediately to each side of the bridge construction site. Red buoy 12 Bravo was placed to the northwest, black buoy 13 Bravo to the southwest, red buoy 12 Alpha to the northeast and black buoy 13 Alpha to the southeast. The two temporary buoys on either side of the construction site (12 Bravo and 13 Bravo on the west and 12 Alpha and 13 Alpha on the east) were less than 350 feet apart. The other, permanent buoys were more than 350 feet apart. Thus, the temporary buoys were compressed relative to the permanent buoy lines. The Coast Guard made no surveys or soundings before placing these temporary buoys. Meisner completed the removal of the bridge on April 19, 1980, and Brown & Root began construction of the new bridge soon thereafter.
The M/V SILVER CITY, owned by Drake Towing Company, passed eastbound through the construction site on November 7, 1981. Brown & Root had begun construction on the south fender system. As it passed between the future locations of the north and south fenders, the tug struck a submerged object and suffered extensive damage. The district court found that the object struck by the SILVER CITY was a large jagged piece of concrete deposited by the blasting of Meisner in demolishing the concrete piers of the old bridge. Covered by four to five feet of water, it was located approximately thirty feet north of the south fender system, outside the project channel but inside the channel marked by the black buoys. The SILVER CITY draws between six and seven feet of water. The Master Loose Leaf Light List in effect on November 7, 1981, represented that the temporary buoys were in water between seven and twelve feet deep.
Drake filed suit in the Southern District of Alabama against Meisner and Brown & Root on August 17, 1982. It added the United States as a defendant on November 17, basing jurisdiction upon the Suits in Admiralty Act (SAA), 46 U.S.C. § 742. See 28 U.S.C. § 1333. Drake settled with Meis-ner and Brown & Root before trial for $42,500 and the court dismissed those defendants from the case. After a bench trial in which the United States was the only defendant, the court found as follows:
Originally, the Coast Guard placed buoys 180 feet apart (aligned with, and marking, the width of the old fender system) to mark the waterway. After the hurricane, the Coast Guard reestablished the buoys in their pre-hurricane position. In March of 1980, however, approximately one month before Meisner Marine had completed its work in the area, the Coast Guard relocated the buoys by moving them from their 180 foot width to a new width of 350 feet.
The court proceeded to hold that the Coast Guard breached its duty of due care in relocating the buoys without first determining the safety of the water in the newly-widened navigable channel. Id. at 285. The record does not indicate that the buoy lines were widened. The permanent buoy lines were originally about 350 feet apart. The Coast Guard simply added four new, temporary buoys. The parties agree that this factual discrepancy should not affect our review of the district court’s decision.
The district court allocated the liability for Drake’s damages as follows: 60 percent to Meisner, 0 percent to Brown & Root, 20 percent to the captain of the SILVER CITY and 20 percent to the United States. Determining Drake’s total damages to be $51,951.52, the court entered judgment against the United States for $10,390, 20 percent of the total damages. Finally, the court denied Drake’s request for prejudgment interest.
The government argues on appeal that (1) the district court was without jurisdiction to determine the negligence, if any, of the Coast Guard and (2) the Coast Guard owed no duty to Drake under the circumstances of this case. Drake cross-appeals the allocation of damages and the denial of prejudgment interest.
The Discretionary Function Exception to the Suits in Admiralty Act
During the pendency of this appeal, the Eleventh Circuit held that the discre
*1064
tionary function exception of the Federal Tort Claims Act, 28 U.S.C. § 2680(a), applies to suits under the SAA.
Williams v. United States,
The SAA provides the sole jurisdictional basis for admiralty claims against the United States.
Williams,
“[I]t is the nature of the conduct, rather than the status of the actor, that governs whether the discretionary function exception applies in a given case.”
United States v. S.A. Empresa de Viacao Aerea Rio Grandense (Varig Airlines),
— U.S. -,-,
Under these principles, the initial decision to place aids to navigation such as the temporary buoys in this case is within the Coast Guard’s discretion.
See
14 U.S.C. § 81. Once such aids are established, however, negligence in their maintenance and operation implicates operational functions and is actionable.
Indian Towing,
The government doggedly insists that
Dalehite
and
Varig Airlines,
both of which were suits under the Federal Tort
*1065
Claims Act, require us to extend the discretionary function exception to the establishment of the buoys as well as to the initial decision to place them.
Dalehite
concerned a federal fertilizer export program. Tons of the fertilizer exploded in the harbor of Texas City, Texas, causing colossal casualties and damages. The plaintiffs alleged no individual acts of negligence but charged negligence in the government’s allowing shipment of the fertilizer into a congested area without warning of the fertilizer’s known explosive characteristics.
Dalehite,
The plaintiffs in
Varig Airlines
predicated their tort claims upon the negligence of the Federal Aviation Administration in certificating certain aircraft for commercial flight. They alleged that the FAA failed to detect and correct particular defects in the aircraft before certificating them. The Court explained that the FAA relies primarily upon the manufacturers and operators to insure that aircraft comply with pertinent regulations. The FAA polices compliance by conducting “spot checks” of the manufacturers’ work. The Court characterized the plaintiffs’ claims as challenging both the FAA’s decision to implement the “spot check” compliance system and the use of that system in the certification of the particular aircraft involved. The FAA had adopted the compliance system pursuant to delegated authority.
Varig Airlines,
— U.S. at -,
Thus, in both Dalehite and Varig Airlines, the Supreme Court held that the implementation of government policies or programs may be shielded from tort liability if the aspects of its performance alleged to be negligent are dictated by guidelines adopted at the policy-making level. Here, the Coast Guard decided to establish the buoys pursuant to official policy. 14 U.S.C. §§ 2, 81; 33 C.F.R. §§ 62.01-1, 62.-25-1. Negligence in that decision is therefore not actionable. We find no authority, however, by which the Coast Guard may establish aids to navigation without first determining the safety characteristics of the water the aids mark. Dalehite and Varig Airlines are therefore inapposite. The government cites other cases to support its argument. We have examined them but they are also unavailing to the government’s case.
The Duty of the Coast Guard
The existence vel non of a duty on the part of the government is a question of law subject to our plenary consideration. The government’s duty in this ease is defined by the Coast Guard’s undertaking. The Coast Guard official immediately responsible for the establishment of the buoys testified as follows:
[The four temporary buoys] were installed subsequent to the removal [of the old fender system] as an aid to the temporary construction that was being conducted in the bridge area---- Those were installed in 1980 to accommodate the bridge construction because they, in *1066 effect, replaced what was originally there during the construction period, namely the bridge supports themselves and the attached fender systems.
Trial Transcript at 72-73. In response to a question as to the purpose of the red and black buoys, the same witness agreed that one purpose was to delineate a waterway safe for vessels with drafts shallower than the depth of the buoys as reflected by the pertinent light list.
Id.
at 83-84. We conclude from this evidence and from the applicable Coast Guard regulations,
see, e.g.,
33 C.F.R. §§ 60.01-5(a), 62.25-1, that the Coast Guard, by placing the temporary buoys, undertook to facilitate safe navigation through the construction area. “[W]hen the government undertakes to perform services which would not be required in the absence of specific legislation, it will be liable if these activities are performed negligently.”
Payton,
The government counters that the lateral buoyage system, see 33 C.F.R. § 62.25-1, is not an undertaking ensuring safe navigation. We agree. Our analysis, however, does not concern the entire lateral buoyage system. We address only the duty assumed by the government in placing the buoys involved in this case. The government also contends that the sole purpose of the temporary buoys was to accommodate the construction, not to aid navigation through the construction site. This argument is specious. Buoys are by definition “aids to navigation.” See 33 C.F.R. § 60.-01-5(a).
The Allocation of Liability
The allocation of liability was proper in this case.
Tringali Brothers v. United States,
The district court relied upon
Leger v. Drilling Well Control, Inc.,
Ebanks v. Great Lakes Dredge & Dock Co.,
Since the plaintiff is entitled to recover ... against either of several tortfeasors, without regard to the percentage of fault [see Edmonds v. Compagnie General Transatlantique,443 U.S. 256 , 260,99 S.Ct. 2753 , 2756,61 L.Ed.2d 521 (1979); The Atlas, 93 U.S. (3 Otto) 302,23 L.Ed. 863 (1876)], it was error for the trial court to distract the juror’s [sic] attention by requiring it to allocate the degree of fault between the defendant and a non-party. If the jury had found the causation in the negligence which it found against Great Lakes, and Great Lakes considered that the total amount of damages for the injuries received by these plaintiffs was disproportionate for it to bear, it could have obtained contributions against Chevron, as it had already undertaken to do, in a different proceeding. That issue was to be tried at a different time and between two live opponents, and not as part of the suit by the injured workmen and representative of a deceased workman against their employer under the Jones Act.
One possible point of distinction between
Ebanks
and this case is that
Ebanks
was a jury case; this case was tried to the bench. Thus, unlike in
Ebanks,
we need not worry about confusing a jury. The distinction is without a difference. The court in
Ebanks
concentrated upon two problems. First, in a trial between Great Lakes and its employees that dealt with Great Lakes’ failure to observe requisite safety precautions, any negligence of Chevron was irrelevant.
Our holding does not leave defendants such as the United States without recourse. In a case that threatens mutual liability, the defendant may implead a third-party defendant “who may be wholly or partly liable, either to the plaintiff or to the third-party plaintiff, by way of remedy over, contribution, or otherwise on account of the same transaction, occurrence, or series of transactions or occurrences.” Fed.R.Civ.P. 14(c). Indeed, the maritime impleader rules were designed to allow the proper allocation of liability in a single action.
See The Hudson,
We therefore remand the case to the district court for him to reallocate liability between Drake and the United States without considering the negligence of Meisner. Ebanks teaches that it is improper for the court to consider in the first instance the liability of a tortfeasor not represented at trial. To allow judgment on the basis of the allocation made by the district court would be to contravene this principle.
Prejudgment Interest
As a general rule, prejudgment interest should be awarded in admiralty cases — not as a penalty, but as compensation for the use of funds to which the claimant was rightfully entitled. Discretion to deny prejudgment interest is created only when there are “peculiar circumstances” that would make it inequitable for the losing party to be forced to pay prejudgment interest.
If the trial court was not clearly erroneous in finding that peculiar circumstances exist, then its denial of prejudgment interest was discretionary. In most instances, we have not found such a denial to be an abuse of discretion.
Noritake Co. v. M/V HELLENIC CHAMPION,
Conclusion
We affirm the district court’s imposition of liability upon the government and his denial of prejudgment interest. We vacate his allocation of liability, however, and remand the case to allow him to reallocate liability between Drake and the United States without considering the responsibility of Meisner.
AFFIRMED IN PART, VACATED IN PART, AND REMANDED WITH DIRECTIONS.
