This is a small boat. The idea is to load hooks with bait through the holes on the top. Then wind back the paddle wheel and send it off to reach the shady, hard to get spots under trees. 

Alternatively, it can be rigged with ‘set and forget’ lines and pulled back on a reel. 

Print with 4 walls to ensure  it's waterproof. low infill on the catamarans and high infill on the paddles and mounting plate. 

Next version will have a hopper that releases liquid bait.
