We tow our 9' Fatty Knees and it's great, glides on the second wave back with negligible drag. I bet it doesn't cost us .25 knts.
Use a Samson floating painter, double-braid with an inner core of polypropylene so it floats. Avoids some prop fouling.
Integral skeg helps it track straight, no slewing around. Hoist it up on deck with halyard and 3-point rig in weather or big chop.
Foam padded 3/4 round 1.5" diameter canvas gunnel guards help prevent deck damage, as well as hull rash when alongside.
We have a 4hp outboard, but usually leave it home and prefer to just row instead. Peaceful.
Granted, we haven't had it turtle, so far, knock on teak.
We "HEART" our Fatty Knees!
