PORTSMOUTH, N.H. — The Coast Guard says the tugboat that sank in the Piscataqua River, forcing two crew members to quickly escape, will be recovered on Friday.

The tugboat Benjamin Bailey is owned by Riverside Marine in Eliot, Maine. The business is a subcontractor to Archer Western, the firm working on the construction of the new Memorial Bridge connecting Portsmouth, N.H., to Kittery, Maine.

It’s not clear why the tugboat went down on Wednesday. Neither crew member was hurt.

Coast Guard Lt. Nick Barrow said divers will take steps Thursday to reduce any further environmental threat. He says a heavy lift barge will retrieve the boat on Friday.
