by Lion Ferry. The service was supplemented between 1973 and 1976 by MS Bolero, however by 1976 both vessels were replaced by the MS Caribe. Lion Ferry sold Yarmouth's second ferry service to Prince of Fundy Cruises who purchased MS Stena Olympica and renamed it MS Scotia Prince. The service underwent another ownership change in 2000 and was renamed Scotia Prince Cruises. In 2004 the company discovered toxic mould in its Portland terminal, owned by the City of Portland, canceling its 2005 season. The City of Portland subsequently canceled the company's lease and evicted Scotia Prince Cruises, thus ending this ferry service. Bay Ferries In 1997 Bay Ferries, a subsidiary of Northumberland Ferries Limited, was the successful bidder for the federal government's Gulf of Maine ferry service. Only the operating licence was transferred as well as the right to be the primary user of the federal government-owned ferry terminals in Yarmouth and Bar Harbor; the service would receive no subsidy from the federal government. Bay Ferries purchased MV Bluenose from Marine Atlantic and used that vessel for the remainder of the 1997 season before selling it. In 1998 Bay Ferries introduced the first high speed catamaran passenger-vehicle ferry service in North America when it purchased HSC Incat 046 from Incat in an aggressive bid to expand the Yarmouth - Bar Harbor ferry service. Throughout the 1990s the market for ferry services in southwestern Nova Scotia was threatened by significant expansions of 4-lane expressways in northern Nova Scotia and across southern New Brunswick so it was theorized that the Yarmouth - Bar Harbor ferry service could maintain market share if the ferry voyage time was shortened. Marketed as "The Cat", the use of the ferry service grew largely due to Bay Ferries' investment and the novelty of riding the ultra-modern high speed catamaran. In 2002 Bay Ferries traded in HSC Incat 046 for a larger vessel HSC The Cat which was also marketed as "The Cat". Beginning in 2003, Bay Ferries began operating HSC The Cat during the winter months on services in the Caribbean. Following the end of the service offered by Scotia Prince Cruises in 2004, Bay Ferries began operating HSC The Cat in 2006 between Yarmouth to Portland, in addition to Bar Harbor; the old Portland ferry terminal being replaced by the newly built Ocean Gateway International Marine Passenger Terminal.
