The Maine Penobscot East Resource Center (PERC) is looking to a new design of lobster boat with a trimaran hull as a “green” solution to the high price of fuel. Present day lobsterboats differ little from their predecessors of 70+ years ago who can easily consume 3,000 galls of fuel annually representing 30 per cent of running costs. Various hull and propulsion configurations were considered but for this application and it was concluded that the best way forward would be a trimaran, which offers a wide beam and therefore large working surface, good stability, yet with the benefits of lower drag. The more efficient trimaran hull configuration may reduce fuel consumption by up to 30 per cent delivering a fuel saving for the lobsterboat of 16 galls per day. [More]

The MAC - Maricuda Atlantic Challenger

A new challenger for the fastest Atlantic crossing is being promoted by Maricuda Marine Technology of the UK. It is the brainchild of naval architect and Managing Director of Maricuda, David Aitken. The concept is a 67 m (220ft) wave piercing trimaran powered by twin GE LM2500 series gas turbines driving Wartsila waterjets via Renk reduction gearboxes. The unusual appearance of the MAC has already earned it the name ‘Concorde of the Seas’, she has a maximum speed of around 70 knots allowing the transatlantic crossing to be made in under two days. To avoid the danger of collision traveling at this high speed, a French system, Automatic Sea Vision, using ocean scanning technology keeps an electronic lookout that will track up to 200 targets simultaneously. Maricuda see commercial opportunities for the design utilising the features of high-speed, safe, long-distance travel in all weather conditions. [More]
