We can throw away our emergency steering system (but haven’t). ![]() The operating principle is the same as for the main autopilot, but is independent of the helm steering system, thereby providing redundancy for this system also. Image 4: L&S Autopilot Hydraulic Linear Drive Unit in Port Hull Image 5: L&S Autopilot Hydraulic Pump in Port Hull We also kept hold of the maintenance kit, which is a bit of a bonus. Our primary autopilot on La Mischief was also a L&S hydraulic system and we were very comfortable with this. Uchimata installed a Leroy and Smitt (L&S) cylinder (See Image 4 below) and a hydraulic pump (Image 5) on the bit arm of the port rudder. So not only did we need a second autopilot in case our primary autopilot failed, we also needed one in case our hydraulic steering failed. FP provides emergency steering for the Saba that you have to stand in the engine room to try and use. It is important to note that if either the hydraulic pump for the steering fails (see Image 1 above), then we also cannot steer the boat with the autopilot either. The autopilot pump will turn the rudders in either direction, and works in a similar fashion to the hydraulic steering that is driven from the steering wheel. ![]() Image 3: Autopilot Hydraulic Pump in Starboard Hull We ordered the Garmin autopilot from FP and this works with a hydraulic pump (Image 3 below), which is installed on the hydraulic circuit of the helm system. The starboard rudder is operated by the hydraulic cylinder and the port rudder is linked by a aluminium bar that joins both rudders together so that they move in unison. Image 1: Hydraulic Pump for Steering Image 2: Rudder Tiller ![]() John previously pointed out this problem to us and its on our jobs list. Note that we need to add a Rose Joint to this arrangement as the board that it is mounted on flexes and we are finding that the stainless steel bolt though the aluminium arm is leaving filings as it turns. The steering wheel operates a hydraulic pump, which itself operates a hydraulic cylinder (See Image 1 below) which pushes and pulls on the starboard rudder stock arm (Image 2 below). On our Saba 50 the steering system is a hydraulic system. ![]()
