Ariele, Stonehorse 23, Electroprop Mariner with custom 38 Volt Lithium Battery Bank

Ariele  will move at about 1 knot with only 1 amp of power – that’s just 38 watts.   This level of power probably sets a record for most efficient drive yet.

Ariele is a Samuel Crocker designed Stonehorse 23.   She was built by the Edey and Duff Yard in Maine.   She is modeled on the lines of late 19th century work boats.   Ariel is a full keel, cutter rigged sloop displacing 4,500 lbs.   She is currently berthed on San Francisco Bay in Marin County.
