A guy near me (Davey Edwards) has started a new big water duckboat company, Bones Boats. His first one is going to be a 22ft powered by a 250hp outboard!! He has progress pics at his website that I figured you guys would want to see. I don't personally know him but, I know a guy who does and I should go take an upclose look. The link brings you right to the pics. Info about him and his company can be gotten to from there.
