“Stone Crusher”

Stone Crusher is a 19’ Gravette and is owned by a grandson of the founder of Gravette Boats in Muskoka Ontario. This boat was a prototype, and is one of only two made. The production boat was shortened to 17’ and marketed as Gravette’s ‘Sunflash’ model. The boat is in for a varnish freshen up and mechanical upgrades. Stone Crusher is named after the hill behind the Gravette plant in Muskoka.
