Mast rotation, a multi-manufacturer solution?
Panbo reader Laurence Woodward built his own 40′ catamaran in Devon, England, and he’d like to use Garmin GMI 10 color N2K instrument displays at both helms. However, his mast rotates and therefore he needs some sort of sensor to keep track of that rotation, which must then be applied to the apparent wind data coming from his masthead vane (or ultrasonic). I doubt that Garmin will develop its own rotation sensor because there aren’t that many rotating masts out there, but then again maybe just a software tweak to their existing rudder angle adaptor might be all it takes. Or perhaps there’s another way? Let’s discuss…
