As Roycv says, steering a compass course may be difficult to allow for drift and tides - GPS will always be accurate, and on the larger yachts we now do not use paper charts but GPS giving us a detailed chart on a screen in front of us as the helm. I am sure that using some of the GPS and radio units as used on drones, you may get a longer range and view of where you are than with our standard RC units? If outside even this range you are in uncharted territory.🤔

Thanks for the input! Will study it more closely.

Good stuff from Ed. We used to have regattas and one used compass steering. If you sail a square you never end up where you started due to wind and water drift.

Hi

Ardupilot supports boats, I have only used it with aircraft but there is a lot of information available applicable to boats on the internet. This is a good starting point.
