A 134-foot U.S. fishing trawler with five crew members aboard was rescued after drifting powerless in heavy seas off Alaska’s coast late last month, but not before a string of mechanical failures turned a routine tow into a days-long ordeal.

According to Undercurrent News, the vessel Great Pacific lost power about 100 miles south of Yakutat on Oct. 27 and was adrift in rough 30-foot seas before being taken in tow by the U.S. Coast Guard cutter John Witherspoon. The situation took a turn when the cutter itself suffered a main engine failure near Kayak Island and was forced to release the tow line, leaving the Great Pacific unmanned and adrift for five days in the Gulf of Alaska.

The Marine Exchange of Alaska in Juneau monitored the vessel’s movements and alerted other ships of the drifting hazard. The organization said the Great Pacific “got eerily close to running aground new Cape St. Elias” before being intercepted by the civilian tug Betty, which towed it safely to Port Etches between the Gulf of Alaska and Prince William Sound.

All five crew members were taken to Yakutat by the Coast Guard on Oct. 29 with no reported injuries. The Great Pacific reportedly lost power due to a broken drive shaft and later underwent an underwater assessment to determine its seaworthiness, Undercurrent reported.
