Looks like a great way to chase the geese around the lake. They need to get the price down though.

 

[Avalanche]

the guy who designed it (an aerospace engineer) says the propeller is 90% efficient at transferring the power from pedal to the water. a canoe oar is something like 20-30% efficient.

2000 dollars is steep though. might as well buy a jet ski

pretty much why I thought a smart guy could hijack the design elements.

There was a plan in popular machnics years ago. I think they used foam for the toons. Why not build one i would if i wanted one and i am 72.

Im suffering from my stupidity rehab right now. I flipped a homemade trike and compressed a disk. My building projects are limited to what I can do in five minute increments. But a fish net singe filled with old coffee cup would be a hoot as pontoons.
