Making the tiller fast and steering w/ the outboard is the best way. In my small (22'') boat, I just straddle the tiller to keep it relatively straight (though with a bigger boat you can lash it: it doesn''t take anything fancy. You just want to keep it from flopping around), and use the outboard swivel for close-quarters maneuveurs: you get steerage at ANY speed, speed control (including DEceleration), and the ablility to throw the throttle handle over hard to act as a stern thruster, if you miss your mark. I don''t consider this un-seamanlike in the marina, w/ currents and wind. If you love your gelcoat. . .
