Maker Pipe boat gear

I live on a lake, but we can't have docks on this lake. The shoreline has a stone sea wall, making it difficult to get my boats into and out of the water, especially since they all have pedal-driven propellers and fins going down into the water15 inches or so.

So I have designed Maker Pipe boat dollies that allow me to cart fully-configured boats down to the waters edge. Then they flip up and become boat ramps. I have built 4 boat dollies and each has a winch for lowering the boat into the water, and pulling it up onto the ramp.

I also have a dozen or so DIY boats with pedal and fin drives and recumbent seats built from Maker Pipe, including a stock Recumbent bike on pontoons with Maker Pipe frame reinforcement.
