The main reasons for having A separate attachment point for the autopilot is to provide system redundancy and the fact that the radial Drive is not adequately reinforced to withstand single point steering forces. On the radial, steering loads are applied to the perimeter of the wheel spread out around the circumference and the casting has reinforced ribs to support the radial loads. If the autopilot ram were to overpower the strength of the radial wheel, the wheel could crack or break rendering both the cable steering and the linear drive ram inoperative. In certain boats like a Landfall 38, there’s just no room for a tiller arm, so folks will build up the radial drive with reinforcement plates above and below the wheel and through bolt the attachment point through 3 layers of metal to mitigate any torsional loads from the ram. Having the ram well aligned will help in this application. Chuck Gilchrest S/V Half Magic 1983 35 Landfall Padanaram MA
