This is great information, Dan!? I'm planning on using an Arduino with GPS to continually track several data points when underway - GPS, RPM, Current Draw, battery measurements, heeling angle (or maybe roll, pitch and yaw), and hopefully at some point, speed through water, windspeed and direction, etc.? But the latter are hard to get access to.??
Oooh, I can't wait to have a boat actually moving in the water again!
