Shoal Draft to Windward
Alan's right, do all you can to get the smoothest keel and bottom surface, and if you don't want to get a folding or feathering prop, at least mark your shaft near the flywheel so you know when the fixed prop is in a vertical position. Shift the transmission into reverse with the the prop vertical as a spinnimg prop is more drag and creates turbulence in front of the rudder so you use more rudder to steer, and it is bad for the transmission to free wheel.
