Here is my method.
Take 100 feet of light line, and coil or flake it on the after-deck. Tie a
"chip" to one end, and make the bitter end fast aboard. Simultaneously kick
the chip over the stern and start a stop-watch. When the line comes taught,
stop the watch.
Now, a nautical mile, for this purpose, is close enough to 6000 feet. So at
one knot it should take one minute to run out 100 feet of line. If it takes
30 seconds, you are doing 2 knots; 15 seconds would be 4 knots; 10 seconds, 6
knots - etc. Just divide 60 by the number of seconds elapsed.
This is much easier than trying to guesstimate when a dropped chip passes the
bow and the stern, and the longer distance traveled makes the result more
accurate. Plus, the chip is recyclable, as you get to haul it back aboard.
