Penguin is a 19′ Bartender which is a unique double-ended planing boat designed by George Calkins. She is one of the last hulls he built and advertised in the back of Woodenboat Magazine issue #109. She is marine plywood on mahogany frame construction. In 2005, she was restored and added the small doghouse, raised windshield and self-bailing cockpit. She is powered by a 40HP, 4-stroke, outboard placed in a motorwell.
