The investigation into how a Montana billionaire's "superyacht" collided with a fishing vessel, killing a 66-year-old man on the smaller boat, may take months to complete, the U.S. Coast Guard said Thursday.
Dennis Washington, known as a Montanan with something of a Midas touch, has an estimated worth of $6 billion, according to Forbes. His assets include the Washington Companies, a copper mine, environmental aviation, a regional railroad and more. He's also the owner of the Attessa IV, a 332-foot behemoth cruiser involved in the fatal crash with the fishing boat last week.
The San Diego Union-Tribune reported Richard Neff, 66, died about four hours after he fell "some distance and struck his head" as a result of the collision.
The Coast Guard posted a video of the rescue online.
The Washington Companies, his business conglomerate, had no statement Thursday on the crash. It's still unknown whether Washington was on board the Attessa when it struck the smaller vessel.
It's also unclear how such a massive boat collided with the Prowler, a 65-foot sportfisher boat.
The Attessa boasts a helicopter landing pad, among other lavish features. According to The Superyacht Times, she was originally built in 1998 as a 300-foot boat, and a three-and-a-half-year rebuild added another 30 feet. The yacht features a large spa, a full-beam gym, sauna, beauty parlor, a 12-seat movie theater, a marble fireplace and a "separate enclosed bar area mirroring the style and glamour of the Hollywood Golden Age," Superyacht News reported after the rebuild.
According to the initial release from the Coast Guard, the Attessa contacted the Coast Guard Sector San Diego's Joint Harbor Operations Center around 7:50 p.m. on Oct. 26 to report the collision, approximately nine miles offshore. A Coast Guard helicopter crew and response boat were on site about an hour later, according to the release, and flew the critically injured man back to San Diego. Responders took 17 passengers back to land while the remaining 10 passengers were transferred to the Attessa, according the Coast Guard.
