Fairhaven Police and the Harbormaster are investigating after a speedboat accidentally launched two occupants from the deck.

The Harbormaster says the boat caught a wave at a bad angle, causing the man and woman to go overboard. The Harbormaster says speed may have been a factor.

The boat was towed in from the harbor at Hoppy's Landing on the West Island Causeway, where emergency personnel tended to the two occupants.

Both people were transported to St. Luke's Hospital for symptoms consistent with hypothermia.

The incident remains under investigation.
