Casualties not involving recreational motorboats Case No. 1.-During a period of low visibility and darkness, an uninspected towing vessel of 222 gross tons pushing four tank barges up the lower Mississippi River was in collision with a downbound foreign tankship. As a result of the collision, the lead barge of the tow was severely damaged, and the foreign tankship burned and became a constructive total loss. Twenty crewmembers of the tank vessel lost their lives. A marine board found that the primary cause of the collision was the failure of the towing vessel to reach a passing agreement. The operator of the towing vessel was unlicensed. Case No. 2.-A 74-year-old tug of 149 gross tons and of iron construction sank in Long Island Sound, N.Y., during a severe winter gale. All of the nine crewmembers were lost. The exact cause of the casualty could not be determined. However, the age of the vessel, lack of watertight closures, and possible lack of stability must be considered as contributing factors. The master was licensed by the Coast Guard. Case No. 3.-A 51-gross-ton uninspected tug was towing a 1,370-ton tank barge about 150 feet astern on a steel towing cable in the San Francisco Bay area. The barge took a sheer. The tug, in an attempt to correct the course of the barge, allowed the towing cable to reach a 90° lead, and the tug was capsized with a loss of one crewmember. The operator was licensed by the Coast Guard. Case No. 4.-An uninspected towing vessel of 94 gross tons was towing three empty tank barges astern on a short hawser in the vicinity of Bolivar Roads, Tex. The towing vessel grounded and was overrun by the barge astern. The tug swamped with the loss of one crewmember. The operator was not licensed by the Coast Guard. Case No. 5.-An uninspected 135-gross-ton tug was assisting an ocean freight ship into a channel. The tug was made fast with one line and was proceeding with the ship. Suddenly, the tug took a list, flooded through the open engine room doors and sank. Although the exact cause of the casualty could not be determined, it is considered the lack of watertight closures and stability were contributing factors. Three crewmembers were lost. The operator at the time of the casualty was not licensed by the Coast Guard. Case No. 6.-An uninspected 147-gross-ton tug was moving anchors for an oil exploration barge off Mexico. A shackle in the towing line parted, and the backlash of the polyethylene towing line killed one crewmember on the tug and injured another. The master was licensed by the Coast Guard. Case No. 7.-An uninspected river towing vessel of 15 gross tons, 40 feet in length, foundered with the loss of the only person on board. Exact cause was not determined, but lack of freeboard and watertight closures are considered to have been contributing factors. The operator was not licensed by the Coast Guard. Case No. 8.-An uninspected towing vessel of 14 gross tons, 41 feet in length, sank in the gulf intercoastal waterway during severe weather conditions. The lead barge on a short hawser astern overran the tug. One of the crewmembers of the tug was lost. The operator was not licensed by the Coast Guard. Case No. 9.-An uninspected towing vessel of 43 gross tons sank in the lower Mississippi River with the loss of three lives. The exact cause of the casualty could not be determined, but it appears the vessel may have been in a glancing collision with a light barge. The master was licensed by the Coast Guard. Case No. 10.-The steering gear of an uninspected towing vessel of 266 gross tons operating on the western rivers failed, and the tow collided with a railroad bridge. The towing vessel flooded through open doors and capsized. One crewmember was lost. The operator was licensed by the Coast Guard. Case No. 11.-An uninspected towing vessel of 18 gross tons exploded while moored to a pier in idle status. The unlicensed master who was the only person on board was killed. The explosion was considered to have been caused by the ignition of propane gas which had leaked from a space heater. Case No. 12.-An uninspected tug of 177 gross tons attempted to cross ahead of a seagoing tankship proceeding up the Mississippi River. The tanker collided with the 70-year-old tug, and it sank in about 3 minutes with the loss of 3 lives. The casualty is considered to have been caused by an error in judgment on the part of the unlicensed operator of the tug. 2. Casualties involving recreational motorboats Case No. 1.-An uninspected tug of 173 gross tons was towing an empty oil barge alongside when it collided with a motorboat anchored near the edge of a channel. The motorboat was destroyed, and one of the four occupants drowned. The tug did not have a lookout posted on the barge. The operator of the tug was licensed as a first-class pilot by the Coast Guard. Case No. 2.-The lead barge of a tow being pushed by an uninspected tug of 53 gross tons collided with a disabled motorboat on the Columbia River. One of the occupants of the motorboat drowned. The accident occurred during hours of darkness, and the tug was not maintaining a proper lookout at the head of the tow. The operator of the tug had a Coast Guard motorboat operator's license. Case No. 3.-At about noon on a clear calm day a river towing vessel of 581 gross tons was pushing 15 barges. Two of the barges were empty and faced bow rake to bow rake in such a manner as to leave a space between the lower parts of the barges. An outboard motorboat with three persons on board was operating back and forth close aboard the starboard side of the tow. The occupants were waving and shouting to the tug crewmembers when, without warning, the motorboat turned and attempted to pass between the rake ends of the barges. The boat was wrecked, and its three occupants drowned. The operator of the towing vessel was not licensed by the Coast Guard. Case No. 4.-An uninspected river towing vessel of 70 gross tons pushing three empty tank barges collided with a motorboat anchored in the channel of a western river. One of the three occupants of the motorboat drowned. The towing vessel was not maintaining a proper lookout at the head of the tow. The operator of the towing vessel was not licensed. Case No. 5.-As a towing vessel of 43 gross tons was pushing four light barges and passing under a highway bridge over a river, an outboard motorboat collided with the lead barge; and the two occupants were killed by the force of collision. The casualty is considered to have been caused by negligent operation of the motorboat. The operator of the towing vessel was unlicensed. Case No. 6.-During hours of darkness, an outboard motorboat collided with the lead barge of a tow being pushed by an uninspected towing vessel of 507 gross tons on the Ohio River. One of the occupants of the motorboat was killed. The investigation reveals that neither the motorboat nor the towing vessel was maintaining a proper lookout and that the navigation lights displayed on the lead barge were not in accordance with the regulations. The operator was licensed by the Coast Guard. Case No. 7.-An uninspected towing vessel of 57 gross tons was pushing a tow in the gulf intercoastal waterway. An outboard motorboat with three occupants on board passed the tow and then attempted to cross the channel ahead of the lead barge. The outboard engine ran out of gas in front of the tow, and before the tow could be stopped, it collided with the boat. One of the occupants of the boat drowned. The operator of the towing vessel was not licensed by the Coast Guard. Case No. 8.-A 26-foot motorboat was drifting on a lake during hours of darkness. The navigation lights were burning, but a proper lookout was not being maintained. A 138-gross-ton towing vessel pushing a 1,278-gross-ton tank barge collided with the drifting motorboat. Two persons on the motorboat were lost. The tug was not maintaining a proper lookout. The operator of the towing vessel was licensed by the Coast Guard. Case No. 9. An uninspected towing vessel of 70 gross tons was pushing a tow on the Tennessee River. An outboard motorboat with two persons on board passed the tow and then attempted to cross ahead of the lead barge. The engine failed in front of the lead barge, and before the tow could stop, it collided with the boat. One of the occupants of the boat drowned. The operator of the towing vessel was not licensed by the Coast Guard.

The operators were unlicensed unless the case summary states otherwise.) 1. Casualties not involving recreational motorboats Case No. 1.-The operator of a 26-foot, 200-horsepower vessel towing a 115-foot dump scow lost control, and the rake end of the dump scow overrode the towing vessel. The operator of the towing vessel died as the result of head injuries received in the accident. Case No. 2.-The operator of a towing vessel engaged in tending a dredge and its dredging pipe was killed instantly when the tug collided with a dredging line forcing the tug's pilothouse door closed, crushing the head of the operator. Case No. 3.-A harbor tug was towing a barge astern on two very short towlines. The barge took a sheer to port, and a towline fouled under the starboard quarter of the tug causing it to list to the port to the point that water entered the hull through opened deckhouse doors. The tug sank with the loss of four lives. Contributing to the cause of the casualty was the slack condition of the fuel and water tanks which reduced the vessel's initial stability. The operator of the tug at the time of the casualty was licensed by the Coast Guard. Case No. 4.-A 25-foot, 240-horsepower towing vessel exploded with the loss of one life. Propane gas was used to heat the tug. It appears that the explosion was caused by the propane gas leaking into the interior of the tug and being ignited by the hot water heater. Case No. 5.-A construction barge being towed by a tug collided with a gas well while the tug was maneuvering to enter a dredged channel. Although the tug operator knew of the existence of the gas well, his vision was obstructed by deck cargo on the barge, and he failed to station a lookout to warn him of his position with relation to the well. The gas well ignited, and two men were drowned while attempting to swim to safety. Case No. 6.-A 39-foot towing vessel foundered during severe weather conditions with the loss of two lives. The tug was loaded with approximately 12 tons of bagged cargo on deck which was to be delivered to a drilling rig. The investigation revealed that the tug sank as the result of severe weather conditions, with its deeply loaded condition and the failure to close weathertight deck doors and ports being major contributing factors. Case No. 7.-A tank barge being pushed by a towing vessel ran aground. While the towing vessel was attempting to tow the barge free, the nylon hawser failed, and a crewmember on the tug was killed by its backlash. The operator was licensed by the Coast Guard. Case No. 8.-A harbor tug was made up alongside a derrick barge. As the result of a wind gust the derrick barge capsized onto the tug. The operator of the towing vessel was drowned and two crewmembers injured. The operator was licensed by the Coast Guard. Case No. 9. The operator of a towing vessel, on watch alone in the middle of the night, lost consciousness, and the tug and tow veered from its intended course and crashed into a causeway. The collision destroyed several sections of the causeway, and a bus plunged through the opening into the lake immediately after the collision. The lives of six persons in the bus were lost. Case No. 10.-A sinking deck barge loaded with oyster shells capsized and sank a small tug which was moored alongside. The operator of the towing vessel drowned. Case No. 11.-An 85-foot tug was assisting a large tankship into a dock. It appears the operator of the tug lost control; as a result, the tug capsized and sank. Three crewmembers lost their lives. The operator was licensed by the Coast Guard. Case No. 12.-During dense fog, tug A. towing a barge alongside, and proceeding at about 3 to 4 knots, sighted tug B almost dead ahead and close aboard. Tug A backed its engines full and attempted to change course to the right. Tug B changed course to the left and increased speed full ahead. Tug B cap sized under the rake end of the barge being pushed by tug A. One crewmember of tug B lost his life by drowning. It is considered that the principal cause of |
