Golden Gate Bridge Highway & Transportation District has selected Mavrik Marine, Inc. to build high-speed passenger ferries as part of their eight vessel Lima Class Ferry Replacement Program. The catamaran ferries will provide transportation services in San Francisco Bay.
The 165ʹ aluminum ferries specifications and systems were developed by Aurora Marine Design in San Diego with structural design from a naval architect in Australia. Construction will begin immediately at Mavrik’s facility in La Conner, Wash. Designed to comply with California Air Resource Board (CARB) Tier 4 emission regulations, the vessels will provide fast, efficient, regulatory compliant passenger service across San Francisco Bay. The District completes upwards of 20,000 trip crossings annually, resulting in approximately two million passenger trips. The eight-vessel Ferry Replacement Program will update the District’s entire fleet over the next several years.
The new high-speed catamarans will carry 500 passengers, accommodate 75 bicycles, and include an ADA compliant elevator, snack bar, and indoor and outdoor seating for passenger comfort, all while cruising at speeds of 39 knots. Powered by six MAN D2862 1066kW Tier 4 engines, the vessels will be outfitted with custom Marine Exhaust Systems DPF/SCR exhaust filter modules. Driveline Services of Portland carbon shafts connecting six Hamilton Jet HTX52 waterjets complete the propulsion system. Traditional diesel generators are replaced by DanFoss gear driven generators, connected to Reintjes/Karl Senner hybrid gear boxes. Electrical storage will be provided by Echandia and McKay will provide electrical outfitting, alarm and monitoring package.
