A Canadian newspaper is reporting that the contractor handling this year’s ferry service between Portland and Yarmouth, Nova Scotia, has found a ship to replace the failed Nova Star. The replacement ship is the USNS Puerto Rico, a ship two-thirds the size and nearly twice as fast as the Nova Star, the newspaper reported. Citing anonymous sources, The Chronicle Herald of Halifax, Nova Scotia, reported Sunday that the replacement operator for Nova Star Cruises, Charlottetown, Prince Edward Island-based Bay Ferries Ltd., has selected the U.S.-built Puerto Rico and is preparing to announce the news soon. The Puerto Rico is 349 feet long, considerably smaller than the 528-foot-long Nova Star.
