ROCKLAND, Maine — Two people were injured when lobster boats collided Monday morning off the Muscle Ridge Islands near Owls Head and South Thomaston.

The two were taken Pen Bay Medical Center with injuries not considered life-threatening after the Thrasher struck the Centerfold about 8:30 a.m., according to U.S. Coast Guard Petty Officer Meghan Canoon.

The two 42-foot vessels were hauling traps in the fog, she said. One person on each boat was hurt.

The Coast Guard has not released the names of the injured, but Centerfold owner Cyrus Sleeper said he was taken to the hospital to be checked. He said he suffered some bruises. He added that two other crew members on his vessel were not injured.

Sleeper said that the hull and wheelhouse of his boat were damaged and that he expects repairs to take two or three weeks.

A fishing vessel helped tow in the Thrasher while Charlie’s Marine Service towed in the Centerfold, Canoon said. Both damaged vessels were taken to Journey’s End Marina in Rockland.

The Coast Guard is investigating the crash, the petty officer said.

The Coast Guard lists the owner of the Thrasher as Robert Baines of South Thomaston.
