1. Power: The standard tiller draws about 1 amp in low to moderate seas state. It can rise to an average of 3 amps in heavy conditions. Peak currents in large quartering seas are about 5 amps.
2. NMEA - Wind mode: As of Aug 2017 the unit will follow an apparent wind line using NMEA 0183 data sentences of MWV and VWR. To use NMEA 2000 a data converter, like an Actisense NGW-1 must be added to your NMEA network. At this time true wind operation is still being evaluated. The manual for the NGW-1 is located at http://www.actisense.com/wp-content/uploads/2017/07/NGW-1-User-Manual-issue-2.04.pdf
3. Can the AP steer catamarans: The Pelagic is steering several cats of a variety of sizes. It is really all about the rudder load. Most cats have very efficient, modern rudders and are relatively easy to steer compared to fin keel mono hull. The unit is routinely steering 10000 kg boats with stern hung, barn door rudders (the Westsail 32 is an example). It has been installed on a Vardo 34' cat and has been in use for about 18 months (Jeff Goff's Vardo - https://www.facebook.com/
4. Mounting the tiller actuator: The dimensions of the pins and spacing on the tiller are common with other manufacturers. The tiller pin should be located 18 inches (457 mm) from the axis of the rudder. The distance from the centered tiller arm and the mounting point on the hull should be 24 7/16 inches (621 mm) for proper operation.
4.1: Tiller actuator compatibility: Tiller actuators currently on the market are all 12 volt motors that depend on reversal of the applied voltage for moving the tiller, or a wheel. The tiller actuators are generally interchangeable.
5.. Gyro operation: The autopilot contains three gyros along with six other sensors to keep track of vessel attitude. The rate gyros supply rudder control to compensate for yaw, roll, and pitch. At the higher gain settings it is quite aggressive with rudder motion.
6. Below deck drive compatibility: Below deck drive are most often driven by 12 volt motors. In some cases 24 volts is used, usually on larger vessels. For this reason, since they usually are 12 volts motors, the Pelagic electronics can drive a variety of below deck or wheel attached actuators. Units that have been attached to the Pelagic include Lecombe & Schmidt, Raymarine, Alpha, NKE, and B&G.
7. Wheel Drive: The Pelagic electronics will easily drive existing wheel based steering motors. The Raymarine systems have been connected to on several vessels.
8. Steel hulls: The Pelagic has been used on several steel hulled vessels. The calibration steps can adjust operation for magnetic field deviations.
