Boasun, that's what autopilots are for --

Night watch -- one watch stander awake
Autopilots ON, boat's on course at six knots.
Quick scan of the horizon.
Duck below -- hit "transmit", let it settle, look at 8 miles (three scans), 4 miles (three scans), 2 miles (three scans), 1 mile (three scans). Hit "standby". Pop back up to the helm.
Quick scan of the horizon.
Elapsed time 90 seconds... distance traveled 300 yards).
Ten minutes later....repeat the above. (Distance traveled since last radar check ~ 1 nm).

Now, if you're in the fog or you can't see the horizon...you reduce boat speed, but the process is the same.

The exercise keeps you young.
