ROCKLAND, Maine — A Massachusetts-based fishing crew is safe after their vessel began taking on water off the Maine coast.

According to the Coast Guard, a distress call was received at 4:50 a.m. Friday from the 120-foot Endurance while it was about 20 miles offshore near Matinicus Island.

The boat, based out of New Bedford, reported that its bilge pumps were controlling flooding but requested an additional pump as a backup. Besides the fishing crew, the boat was carrying a research team from the National Oceanic and Atmospheric Administration.

A 47-foot Coast Guard rescue vessel reached the fishing boat at about 6:25 a.m. and towed it to Rockland.
