NEW BEDFORD — A 65-year-old city man suffered head injuries in a collision at sea Wednesday morning with the fishing vessel Reflection, authorities said.

The skipper of the 19-foot Marta and Gina, who was not identified, was brought to Pier 3 on the city's waterfront by the New Bedford Fire Department's boat and then transported by ambulance to St. Luke's Hospital, according to Major Pat Moran of the state Environmental Police.

The collision with the fishing vessel Reflection, based in New Bedford, happened about 9:50 a.m. at Phinney's Ledge in the shipping channel outside New Bedford Harbor, he said. The fishing vessel contacted the Coast Guard and reported it had been involved in an accident with a small pleasure craft.

Details of the collision were not available, although Moran said visibility was less than 100 yards at the time of the accident.

The accident is under investigation by the state Environmental Police and the Coast Guard.

Authorities found the pleasure craft alongside the fishing vessel and the skipper of the Marta and Gina had suffered head injuries in the collision, he said. There were blood stains inside the cabin of the Marta and Gina.

There was extensive damage to the bow of the Marta and Gina, and the fishing vessel suffered "a pretty good size dent" in the port side, Moran said.

The pleasure craft was towed to Pease's Park in Fairhaven by Tow BoatU.S. of New Bedford.

Responding to the scene were state Environmental Police, the New Bedford Police Department, the New Bedford Fire Department, the Fairhaven Harbormaster and Tow BoatU.S.
