boats & sailboats

EVA has been helping convert boats to electric as well as electric sailboat auxiliaries for almost 20 years.  Our largest  electric auxiliary is a 144V system for a 50 ft sailboat built in Nova Scotia.  Our largest pure electric boat was a 40 ft Electric Boat by Clearwater Boats built in 1994.

EVA has done a number of auxiliary drives replacing older Atomic 4, Westerbeke, and other diesel engines.  The typical system is 48V.   There are two reasons.  First, a 48V system can drive a 28 ft sailboat with 8000 lbs displacement.  A 48V system is rated at 6 hp continuous and 10 hp peak. Other 48V systems are 10 hp continuous and 30 hp peak.  A generator can be added to make it an electric hybrid.  Second, above 50V, the U.S. Coast Guard has more stringent regulations; these regulations are more applicable to commercial vessels.

EVA can provide boat calculations to help you size components.  There is a misconception that:

            1 hp electric  = 3 hp gas.  

                   This is not true.  

Hp is hp.  The difference is that an electric motor is rated at it point of maximum efficiency; yet may be capable of delivering 3x its rating for short periods of time (i.e. Startup, acceleration, etc.)
