and the NW Channel light a couple of times. The charts give an exact waypoint at each end, and a nice line showing exact course, and reciprocal between the two.
And MANY boats lock the way point in, set the auto pilot, and let'er run. Oh, and since it's on course, and it's wide open out here- lets go down and make a sandwich. Or something!
After I had two big power cruisers pass me way close (one less than 50 feet away) running full bore (with NO ONE in sight on deck), I moved my ass about a mile SOUTH of that rhumb line, and set new navigation up. And yes, I saw them coming and dodged.
No more close misses.
Since them I have NEVER run the exact rhumb line shown on the charts, in big open waters.
I've said for years now that someone was gonna have a head on on the Great Bahama Bank, and nobody would know for hours!!
