Yacht Attessa IV and sportfishing boat collide near California and Mexico coast


By Dorie Cox

A collision between the 332-foot (101m) M/Y Attessa IV and the 65-foot commercial sportfishing boat Prowler resulted in one death and several critical injuries on Friday (Oct. 26).

The crew of Attessa IV reported the incident at about 7:50 p.m. about nine miles offshore of Imperial Beach, off the Pacific coast near the California and Mexico border. It appears that Attessa IV was heading south. According to its website, Prowler was on an overnight trip with 22 anglers from its homeport in San Diego.

U.S. Coast Guard Sector San Diego dispatched a MH-60 Jayhawk helicopter crew and a 45-foot response boat, and arrived on scene about 8:45 p.m. They transferred 17 of the 29 people onboard from Prowler to USCG Sector San Diego. One critically injured passenger was flown to emergency responders for transport to UC San Diego Medical Center – Hillcrest. He later died. Prowler’s captain remained on board, and the remaining 10 passengers were transferred to the Attessa IV for return to San Diego.

The Coast Guard Cutter Sea Otter was also at the scene and waited with Prowler for commercial salvage, according to a statement from the USCG. The USCG reported “extensive damage to the starboard quarter of the sportfisher and multiple injuries.” The incident is under investigation.

M/Y Attessa IV was originally launched in 1999 as Evergreen from a commercial shipyard in Japan. Attessa’s owner bought it about 10 years ago, brought it to Vancouver Shipyards, stripped and rebuilt it. The new Attessa IV launched in 2011.
