The high-speed ferry known as The Cat sits at the Ocean Gateway Terminal in Portland in this June 2016 file photo. Bay Ferries, which operates the vessel, again has delayed the expected start time for operating the ferry between Bar Harbor and Nova Scotia.

Because of ongoing construction in Bar Harbor, a Canadian ferry operator again has delayed the expected start date of ferry service between Maine and Nova Scotia.

Bay Ferries said Monday that β€œthe earliest date on which any service could commence is in the late summer range.”

The service β€” which for the past 10 years has either not operated at all or operated between Portland and Nova Scotia β€” had been projected to start operating from Bar Harbor in late June.

All customers with reservations this season are being offered full refunds and, if available, alternate booking on the Fundy Rose ferry, which operates between Saint John, New Brunswick, and Digby, Nova Scotia, the company said. No new reservations for The Cat ferry will be accepted until Bay Ferries has a more firm start date for when service can get under way.

So far this summer, more than half of customers who had reservations for The Cat have accepted bookings on the Fundy Rose instead, company officials said.
