Rhode Island's Blount Boats has cut a deal to build two crew transfer vessels to support US offshore wind farm projects.

The shipyard will build the ships for Atlantic Wind Transfers based on UK-based Chartwell Marine's Chartwell 24 ship design, modified for operation in the US northeast. They will be delivered in 2020.

"As the offshore market grows, so too does the demand for American-made [crew transfer vessels]," said Blount president and finance chief Marcia Blount.
