    Jerry Powlas

    Jerry Powlas and his wife Karen Larson, began sailing together in 1990 and founded Good Old Boat magazine together in 1998. Retired these days, they still have too many boats and a long list of ongoing boat projects. They sail Mystic, their C&C 30, on Lake Superior and Sunflower, their trailerable Mega 30, during the shoulder seasons.
