Sometimes you seek inspiration. Sometimes inspiration smacks you in the face. As I was walking down the clearance isle at Walmart, I was smacked in the face. They had a few kid’s kickboards on clearance. With my Mini Alligator Tours airboat experiences still fresh on the brain, I immediately thought that one of these kickboards could be the starting point of a scratchbuilt airboat.
There were a few features of this kickboard that I particularly liked, in addition to its clearance price. First of all, it has a very wide stance. That would serve to prevent tipovers--hopefully. Another appealing aspect was its slippery plastic shell. I thought that would help it slide the water, as well as grass and other surfaces. The other kickboards that I saw had a nylon mesh-type covering. That’s probably great if you are actually using it as a kickboard, but not so great in airboat mode.
The one thing that I did not like about the kickboard was its very pronounced curvature (as viewed from the side). Most airboats use flat-bottomed hulls. I figured I would give it a try anyway and see what happened.
Keeping It Simple
Early on, I decided that my focus with this project would be to make the simplest airboat that I possibly could. That proved to be a surprisingly elusive goal. I discarded numerous design sketches over the course of an afternoon before I felt that I had shaved my concept down to the bare essentials.
