I haven't thought of this in years, but I think you guys would be interested in it. One day I was at a small lake around here, and this guy comes putting around the corner in a minature tug boat ! I wish I had a camera. he was sitting inside of it ,looking out of a scaled down windshield, he was completely enclosed ...I would guess it was no longer than eight feet, no wider than four foot. And it was all tricked out like a nice scale model . Have you ever seen anything like it ? It was sitting deep like a real one and pushing a big fat wake off the nose as it chugged along...It looked kind of fun actually. Maybe a future project someday....
