Review of a new autopilot from Nautamatic. It has some innovative features, probably appealing to many boat-owners.
“A rudder sensor is an electro-mechanical device stuck in a remote, unfriendly area of a boat. It’s a pain to install and subject to comparatively high failure rates, so not having one is definitely a good thing. But how does the TR-1 work without it? That’s the subject of speculation and skepticism among other autopilot manufacturers.”
