I keep windsurfing rigs at their house and will adapt the boat so we can fit them on easily. We'll be adding a rudder, side boards, and an adapter to drop the mast in and hold it in place.
We also have a 40 year old seagull in the garage which we'll bring back to life and also a couple of old electrics which I may start him out with but the primary propulsion will be oars followed by the sailing rigs. What's nice is I have all different sizes pre-rigged that I use for windsurfing so we've got sail rigs for all wind conditions.
