Re: Information while racing around the buoys
Because I have an autopilot with a heading compass, I get a lot of good info regarding current and drift...which is factored into my COG (course over ground) readout. By calculating the difference between Magnetic compass heading and the COG, I can usually figure out if we're getting into the gulfstream or fighting eddys.
Its always good to know your tack angles factoring in COG
