A Coast Guard helicopter crew rescued two Molokai fishermen after their 22-foot recreational boat capsized off Molokai Wednesday, the Coast Guard said.

The men ages, 47 and 52, told the Coast Guard their boat was about 100 yards offshore from Kukaiwaa Point on Molokai’s north side.

An Air Station Barbers Point-based Coast Guard helicopter happened to be on a routine training mission when two uinjured men flagged it down by using hand signals, the Coast Guard said.

The men were on the beach near Kukaiwaa Point.

A Coast Guard rescue swimmer was lowered to the beach and assisted the men, who were airlifted to the Molokai airport.

The men informed the swimmer that a wave swamped and overturned their vessel at about 1 a.m. Wednesday.

The men will coordinate the salvage of their vessel, the Coast Guard said.

About 50 gallons of gasoline was left onboard, but there was no sign of pollution, the Coast Guard said.
