USERS’ PLATFORM Applications Green motor for revolutionary catamaran Sailing-class catamaran manufacturer African Cats has just announced the development of a new generation of catamarans – the Green Cat. These crafts are propelled by a revolutionary new motor that uses no fossil fuels and generates its own power from the waves. he Green Cat is a luxurious and spacious sailing-class catamaran that can reach top speeds. The difference is that it is the only sailingclass catamaran without a fossil-fuel engine. Instead, it is powered by an environmentally-friendly electric generator and motor – the Green Motion electric propulsion system. This innovation allows sailors to power their catamarans in an environmentallyfriendly way. “Apart from propelling the craft when there’s no wind, this motor powers the air conditioning, the heating, the lights – it provides electricity for the whole boat,” T says company founder and Director Gideon Goudsmit. “The Green Motion system also produces its own power: when the catamaran is sailing under wind power alone, the motor becomes a dynamo, generating and storing electricity. And when the battery’s full and there’s plenty of wind, the motor can be lifted out of the water for a more streamlined shape and faster sailing.” Focus To make their ultra-lightweight catamarans, African Cats use: • vacuum infusion to construct each structural component – not just the hull, • Twaron fibre instead of glass fibre for reinforcement, • a unique foam that absorbs 78% less resin, • lightweight epoxy resin instead of traditional polyester resin, • a spray-paint coating instead of a heavy gel coating, saving 8% in weight. motors. An electric motor that could propel a normal catamaran would be huge, increasing the craft’s weight even further and slowing it down so much it would hardly move. What’s more, with luxuries like cappuccino machines and king-size bedrooms onboard, each cat would have a very heavy interior. This meant that, to reduce the craft’s weight enough, not only did every piece of furniture and each little accessory need to be super light, but the weight of the craft’s entire structure also needed to be vastly reduced. Critical weight This combination of luxury, highpowered sailing and green electric power is unique to the Green Cats. “We’ve been building light, fast and luxurious catamarans for seven years,” says Gideon, “and although they were lighter than other sailing-class cats, our cats still needed the impressive power-to-weight ratio of a fossil-fuel engine to get them moving.” To combat this problem, African Cats have reduced the weight of their catamarans from 8,900 kg to just 5,000 kg. Without such a light structure, it wouldn’t be feasible to use electric The only sailing-class catamaran without a fossil-fuel engine. Creative solutions African Cats first looked at using vacuum-infusion technology to reduce weight. With this method, each layer of the hull is assembled inside a mould and jec composites magazine / No45 November-December 2008
