In this admiralty case involving a collision on inland waters, Brown Marine Services, Inc., appeals (1) the determination by the United States District Court for the Southern District of Alabama that Brown Marine's tug was the sole proximate cause of the collision and (2) the amount of damages awarded by the district court to the appellees, 651 F. Supp. 187. Employers Insurance of Wausau, Self Towing, Inc.'s insurance company, cross appeals the amount of damages the district court awarded it. We affirm as to the liability issue and reverse and remand as to both of the damages claims.

M/V BLACK JACK, a tugboat, was owned by KJI, Inc., and was under bareboat charter to Self Towing.1 BLACK JACK and her tow were moored at a shell unloading site along the North bank at or near mile 271 of the Gulf Intracoastal Waterway. The site is approximately 300 feet west of the West Bay Bridge, a lift drawbridge located in West Bay, Florida. The bridge opening is approximately 86 feet wide and is located in the middle of the 125-foot channel. The channel runs straight through the bridge opening.

Although the day was clear when BLACK JACK's tow began unloading, a dense fog night eventually enshrouded the site. M/V ERNEST H. DOSS, Brown Marine's tugboat, was traveling through the West Bay Bridge and pushed the first of its tow, an empty oil barge, into BLACK JACK.

BLACK JACK was declared a constructive total loss pursuant to a hull insurance policy between Self Towing and Wausau. Self Towing then sued Brown Marine and Wausau intervened. The district court found DOSS's actions to be "the proximate cause" of the collision, and awarded damages. This appeal and cross-appeal followed.

It is a well-established rule that a moving vessel which strikes a stationary vessel is presumed to be at fault and has the burden of proving otherwise. See, e.g., The Oregon, 158 U.S. 186, 197, 15 S. Ct. 804, 809, 39 L. Ed. 943 (1895); Mount Washington Tanker Co. v. Wahyuen Shipping, Inc., 833 F.2d 1541, 1542 (11th Cir.1987). Brown Marine's DOSS thus is presumed at fault for hitting the moored BLACK JACK.

It is similarly well established under The Pennsylvania rule that "when ... a ship at the time of a collision is in actual violation of a statutory rule intended to prevent collisions, ... the burden rests upon the ship of showing not merely that her fault might not have been one of the causes, or that it probably was not, but that it could not have been. Such a rule is necessary to enforce obedience to the mandate of the statute." The Pennsylvania, 86 U.S. (19 Wall.) 125, 136, 22 L. Ed. 148 (1874).

In the present case, the district court found that in light of the restricted visibility from the dense fog, DOSS's failure to maintain a proper lookout violated 33 U.S.C.A. Sec. 2005. Similarly, the district court found the actions by DOSS's captain in proceeding without a lookout and without ascertaining the existence of lights in an area he knew was used to unload materials violated 33 U.S.C.A. Sec. 2007(a). Brown Marine does not challenge these findings and conclusions. Rather, although admitting DOSS was a cause of the collision, Brown Marine disputes the district court's determination that DOSS was the cause of the collision.

Brown Marine argues that BLACK JACK violated various statutory provisions and thus Self Towing was under an obligation to prove that these violations could not have been a cause of the collision.2 The district court expressly and implicitly rejected each of Brown Marine's affirmative defenses. We affirm.

Brown Marine raised an affirmative defense that BLACK JACK violated 33 U.S.C.A. Sec. 409,3 33 U.S.C.A. Sec. 2009(g),4 and 33 C.F.R. Sec. 162.75(b)(3)(i).5 The touchstone for a violation under these three provisions is that the offending vessel obstructed the passage of another vessel.6 Brown Marine argues that the district court erred in finding that "[t]he plaintiffs' flotilla was not moored or made up in the channel in such a fashion so as to obstruct the channel." See 651 F. Supp. at 188.

We examine whether this finding was clearly erroneous. Harbor Tug & Barge, Inc. v. Belcher Towing Co., 733 F.2d 823, 825 (11th Cir.1984). "Whether ... [a] mooring constitutes an obstruction to navigation is to be determined by reference to all the relevant facts and circumstances...." Orange Beach Water, Sewer and Fire Protection Auth. v. M/V ALVA, 680 F.2d 1374, 1380 (11th Cir.1982). Our review of the record convinces us that the district court's finding was not clearly erroneous.

Brown Marine raised an affirmative defense that BLACK JACK violated 33 U.S.C.A. Sec. 2030. Section 2030 requires "a vessel at anchor" to display all-round lights. BLACK JACK, while moored, did not display all-round lights.

Self-Towing countered that Section 2030 does not apply to moored vessels. We agree.7 In Garrett v. Higgenbotham, 800 F.2d 1537, 1539 (11th Cir.1986), this Court insisted on a strict construction of the Inland Navigational Rules Act of 1980:

The INRA is an elaborate and sophisticated network of interlocking, technical, statutory regulations governing waterborne traffic generally. Moreover, it is based, in large part, on a similar body of international regulations.... Especially in light of the history, courts ought to be extremely slow to tamper with this sensitive, regulatory system. This is true even if it seems reasonable, in the context of an isolated case ... to require [safety devices] when the statute has not done so.

Section 2030 by its express terms applies to a "vessel at anchor." Because "vessel at anchor" and "moored vessel" are not synonymous terms of art,8 we hold that Section 2030 does not apply to moored vessels. See Dahlmer v. Bay State Dredging & Contracting Co., 26 F.2d 603, 605 (1st Cir.1928) (The First Circuit held that 33 U.S.C.A. Sec. 180, Section 2030's predecessor, did not apply to moored vessels: "We cannot sustain the contention that a moored vessel is subject to the same rules, relating to lights, as those applying to an anchored vessel. It is the doctrine of the courts that no analogy can be drawn between anchored vessels and moored vessels in this connection."). In addition, we discern from the legislative history associated with Congress's recodification of Section 180 to Section 2030 in 1980 that Section 2030 does not apply to moored vessels. See S.Rep. No. 979, 96th Cong., 2d Sess. 22, reprinted in 1980 U.S. Code Cong. & Admin. News 7068, 7089 ("Anchored vessels do not include barges moored to a bank or dock. Lights for these vessels may be included in the to-be-developed Pilot Rules of Annex V.").9

Brown Marine also raised an affirmative defense that BLACK JACK violated 33 U.S.C.A. Sec. 2035(f), which provides that in or near an area of restricted visibility "[a] vessel at anchor shall at intervals of not more than 1 minute ring the bell rapidly for about 5 seconds."10 BLACK JACK never rang the bell. Because Garrett requires strict construction of the language of any Inland Navigational Rule, we conclude that, although Section 2035(f) applies to a vessel at anchor, it does not apply to a moored vessel.11 See Pennsylvania R.R. v. Central R.R., 103 F.2d 428, 429 (2d Cir.), cert. denied, 308 U.S. 591, 60 S. Ct. 121, 84 L. Ed. 495 (1939).

Brown Marine raised the affirmative defense that BLACK JACK failed to monitor radio communications as required by the Vessel Bridge-to-Bridge Radiotelephonic Act, 33 U.S.C.A. Secs. 1201-1208.12 Brown Marine seeks to ground its defense in 33 U.S.C.A. Sec. 1203(a)(4), which provides that the Act applies to "every dredge and floating plant engaged in or near a channel or fairway in operations likely to restrict or affect navigation of other vessels." Brown Marine argues that BLACK JACK falls within the definition of floating plant. We cannot agree that BLACK JACK fits within the definition of "floating plant" we borrow from 33 C.F.R. Sec. 161.103 (" 'Floating Plant' means any vessel, other than a vessel underway and making way, engaged in any construction, manufacturing, or exploration operation, and which may restrict the navigation of other vessels.").13 3]

The district court found that BLACK JACK had a fair market value of $225,000. The district court also noted that BLACK JACK was insured for $70,000 pursuant to a hull policy between Self Towing and Wausau. Finally, the district court noted that Wausau received two repair bids, one for $70,854.16 and the other for $98,000. Because repair costs exceeded the insured value, the district court awarded damages equal to BLACK JACK's market value. The district court awarded Self Towing $155,000 and awarded Wausau $70,000 because Wausau had already paid that amount to Self Towing pursuant to their hull insurance policy.14

Brown Marine contends the district court erred in the amount of damages awarded. We agree that the district court confused the concept of constructive total loss for insurance purposes with the concept of constructive total loss for tort damages purposes.

Insurance policies frequently provide that a vessel is declared a constructive total loss when repair costs exceed the insured value. The rule for tort damages, however, differs: "The legal principles are well settled: A vessel is considered a constructive total loss when the cost of repairs is greater than the fair market value of the vessel immediately before the casualty." Ryan Walsh Stevedoring Co. v. James Marine Services, Inc., 792 F.2d 489, 491 (5th Cir.1986). In the present case, the repair bids15 are far less than the $225,000 fair market value. Consequently, we conclude that the district court erred in its method of determining damages and we remand for the district court to determine damages pursuant to the correct legal standard.16

When Self Towing sued Brown Marine, Wausau intervened as Self Towing's insurance company. If Self Towing successfully sued Brown Marine, Wausau sought subrogation for its expenses connected with Self Towing's claim under the insurance policy. All parties stipulated that Wausau was entitled to an award equal to the amount set forth in Intervenor's Exhibit 11.

In its initial judgment, the district court awarded Self Towing $225,000 without addressing Wausau's claims. The district court then entered a second judgment in favor of Wausau for $70,000, thereby reducing Self Towing's recovery to $155,000. The district court awarded Wausau $70,000 because the insurance policy required Wausau to pay that amount to Self Towing for BLACK JACK's hull damage.

Wausau cross appeals the amount of damages awarded it by the district court. We agree with Wausau that the district court did not tailor its award according to the stipulated amount set forth in Exhibit 11. Consequently, on remand, the district court must so tailor its award.

Accordingly, AFFIRMED in part, and REVERSED and REMANDED in part.
