A Coast Guard MH-65 Dolphin helicopter crew from Air Station Barbers Point, Hawaii, rescued three men and a dog after the 70-foot catamaran Brandi Anne sank about 40 miles northeast of Oahu’s North Shore on Aug. 9.

The captain made a mayday call to the Coast Guard at 12:44 p.m. to report that the Brandi Anne was sinking. The crew left the catamaran for a life raft.

Take a look at this Coast Guard video of the successful operation.

“Our crews train regularly to conduct just this kind of rescue and these mariners helped themselves by being prepared with a life raft and life jackets,” said Lt. Patrick Frain of Sector Honolulu. “We always recommend mariners carry a VHF-FM radio so they can contact the Coast Guard if the need arises, like it did today.”
