Coast Guard Station Menemsha joined a 72-hour search effort for two fishermen who went missing off Block Island Tuesday morning when their vessel capsized.

The search was suspended by the end of the day Wednesday, the Coast Guard said.

The two fishermen were on board the vessel Mistress when it capsized and sank early Tuesday. The mayday call came in at 1:30 a.m., according to a Coast Guard press release. The Mistress is home ported in Point Judith, R.I.

The fishing boat Captain Bligh initially responded to the scene and rescued one fisherman from a lifeboat, the Coast Guard said.

A search was launched for the other two fishermen that included crews from Coast Guard cutters Sanibel, Steelhead, Escanaba and Albacore, along with Air Station Cape Cod MH-60 Jayhawk helicopter crews, HC-144 Ocean Sentry airplane crews, 45-foot response boat crews from station Point Judith and 47-foot motor lifeboat crews from station Menemsha.

The search covered 2,152 square nautical miles, the Coast Guard said.
