In the December / January issue of the Professional Boat Builder magazine, the dominant resource in the field of recreational marine technology, Nigel Calder published a thorough, 12-page report on the hybrid marine systems from the first beginnings a decade ago to the most recent developments. The author, a contributing editor of the magazine and a member of the American Boat & Yacht Council’s Electrical Project Technical Committee, introduced the topic with the following remark: Though the hype around marine hybrids died down after early failures, the development of these systems has persisted. The results include some viable and almost-viable power choices for the recreational marine market.
Among projects which have hit the sea the contribution of J&J Design deserved a special mention: … By far the most successful implementation of the parallel approach is to be found in the Greenline series of powerboats … In the second part of the article the author discussed several different approaches, from low-consumption systems in U.K.’s canal narrow boats to the modern “hour of power” concept in superyachts, where the idea is … to provide these boats with sufficient battery-powered electric propulsion to enable operating at up to 10 knots for one hour to get in and out of harbors and anchorages, resulting in zero emissions.
An accent from the conclusion: One way or another, the combination of technological advances (especially in lithium-ion and lead-acid batteries), dogged perseverance, and an increasing body of real-world experience is finally delivering reasonably well-tested and proven parallel and serial hybrid systems.
