The lines and VDH tell me it's a SeaCraft, but the transom has definitely been molested at some point in the past. Looks like it may have the script SeaCraft emblem on stbd quarter, which is what Moesly used (Similar to the ones Carla sells on the Moesly SeaCraft site.) Check out the Moesly vintage brochures at
