The Shannon Defiance 38’ is available with a flybridge or as an express yacht, and is the solution for powerboat owners seeking to be environmentally conscientious and reduce their carbon footprint.
The patented hull design licensed by SRD Hull Tech enables the Defiance 38 to reach speeds in excess of 25 mph with one half the engine horsepower of comparable powerboats. The unique hull shape gives an exceptional flat ride plus excellent all-around performance in waters just 2 feet deep. The speed-to-horsepower ratios and fuel economy of the Defiance 38 are extraordinary when compared to semi-displacement and deep V hulls, making the Defiance 38 truly one-of-a-kind. With only twin 150HP diesels, the prototype reached a top speed of 21 knots and cruised at 18 knots burning only 11 gallons an hour total, for a fuel burn of about two miles to the gallon.
The Defiance 38 is perfect for the latest engine pod systems like the Cummins/MerCruiser Diesel Zeus system or the Volvo IPS. Conventional propeller drives are also available in either single or twin engine configuration and for anyone interested in innovation, Walt has some ideas about a triple engine configuration.
