I own a 2003 38 Open w/450 Diamond Cummins and troll Long Island Sound with no rudder extensions and the boat tracks well on autopilot... I even run at times on a single engine w/autopilot and have not experienced a problem maintaining heading although the seas are only 1-2 ft w/currents... I've seen several posts relating to increasing rudder size but I'm not a fan of that.... Suggest you review the autopilot system gains to see if they are set correctly.. M2C
