The Honolulu Fire Department’s helicopter airlifted two men from their 19-foot motorboat early this morning after waters in Kaneohe Bay became too rough.

The boaters called the fire department at 12:40 a.m. after their boat experienced mechanical problems about a half mile east of Mikolii Island.

Capt. Terry Seelig, the fire department spokesman, said the two men planned to spend the night in their anchored  boat after its engine broke down, but the ocean conditions apparently became too rough.

The helicopter took the two men to Heeia Kea pier at about 2:44 a.m. There were no injuries.

The National Weather Service has issued a small craft advisory for Hawaiian waters because of strong tradewinds and rough seas of seven to 14 feet in waters exposed to the wind and wind swell.
