Electric autopilot hook up to the Monitor
A small inexpensive tiller pilot, with low power consumption, can be hooked up to the Monitor counter weight or to a 10 inch (25 cm) stump substituting for the regular airvane. Instead of having an autopilot turn the boats large rudder you are only asking the autopilot to turn the small semi balanced Monitor servo oar. This oar will then turn the boats rudder with the water flow providing the power. This way you can steer even a 60 ft boat with a small autopilot The least expensive tiller pilots can push 80-100 lbs., but only a couple of pounds are actually needed for this hook-up to work. If you go up to the next level of tiller pilots, you can have remote control or a separate compass unit that can be placed out of the weather and at a place that is easy to reach.
This autopilot hook-up has many advantages and would be preferred when you want to follow a magnetic compass course rather than the wind direction. The autopilot can also be interfaced with the GPS. When there is no wind and you are under power, or in extremely light air, the combination autopilot/windvane might be the best possible way to achieve perfect self-steering with minimum power consumption. This was initially invented because many windvanes have difficulty to steer downwind. If you want to protect the small tiller pilot and keep it away from saltwater, you can put it in the lazarette and connect it to the Monitor with a small Morse cable. It is up to each individual owner to work out the best arrangement since every boat is different.
The very sensitive Monitor, together with a good skipper, should be able to self-steer without the use of the autopilot - especially with the much larger light airvane. In our opinion, this provides personal satisfaction, is quieter and more related to sailing. Call it a challenge.
