Stimson Yacht Design and Naval Architecture (Auckland, New Zealand) has announced that it has been engaged to help design New Zealand’s first all-electric passenger ferry. The company has formed a joint venture partnership with Malcolm Tennant Designs (French Bay, New Zealand) and Kit Carlier Designs (Auckland, New Zealand). Named SSC Marine Ltd. (Auckland, New Zealand), the company will focus on designing high efficiency catamaran commercial ferries.
The company announced its involvement as naval architects for New Zealand’s first all-electric passenger ferry.
Their goal is to produce the next generation of high efficiency catamaran hull forms for SSC Marine, building on the Tennant database drawing on their 30 years’ experience, methodical approach and using current design tools such as in-house CFD.
The 18.5m 130 passenger ferry for a cross-harbor route will be all-carbon/foam construction engineered by Gurit APAC in Auckland, assembled from CNC-cut infused panels, with only the lower hulls being molded. The flat panel topsides construction lends itself to the Kit Carlier chiselled look and in this way tooling costs are minimized, assembly time sped up and structural weight reduced to enable the electrical propulsion system to be viable. The vessel will operate at 20knots service speed, running at the rush-hour peak three back-to-back 25-minute runs with 5-minute dip charges at one side only before a 1hour recharge is required.
The adoption of full carbon/foam construction is the enabling technology which when combined with the highly efficient canoe-stern hull form reduces the resistance and so allows the weight (and therefore cost) of batteries to be minimized. The life-time costs of the vessel’s energy consumption and maintenance costs are reduced to the extent that the higher initial construction costs are paid back well within the operational contract time-frame, and a higher profit per passenger per trip is returned.
