Re: Boating Anyone
If it were a canoe I would use the axle set up made for portaging a canoe. It is small and attaches to the canoe itself. At the pulling end I'd make up a hitch coming directly from the bow. No need to make a frame as the canoe is plenty strong as it is. Don't know about kayaks, but I would think the same is true. The canoe rig is set up so that the wheel/axle folds up and stows inside the canoe. Just a thought.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
