ROCKLAND — Maine is adding a new ferry to its fleet that serves the state’s islands.

Friday’s event in Rockland marks the first time in 19 years the state ferry service will add a new ferry to its fleet. The Capt. E. Frank Thompson, named after a former long-time ferry skipper, is being christened at the Rockland Ferry Terminal.

State transportation officials say the new $10.3 million vessel can transport up to 250 passengers and 22 vehicles.

A number of family members of Capt. Thompson plan to attend Friday’s event. His daughter, Than Hopkins, will christen the vessel.

Elected officials and their representatives will also attend.
