A sailboard rig is going to be a winner on looks and also efficiency, but everything else about this boat has got to look cool and be efficient too – in order to match that sail in the kids minds, even the daggerboard and rudder have got to have a little something about them. It also has to be a sit-on boat rather than a sit-in one. The basic dimensions close I have chosen are close to those of a couple of plastic mass-produced designs aimed at the young and intended for the same sort of purpose as here.
