Dead Reckoning
#3
As long as the boat has forward speed of at least a knot my log line method will take no longer than 35 seconds.  But at the cruise speed of a midsized yacht,  say 7 knots, the line will fully extend in only 5.1 seconds.

Ive seen your pdf and its just fine, but it takes two people; one to drop the chip and one to time it's passing the stern.    My line method can be accomplished from the cockpit solo and more closely simulates the original log line proceedure that took three people or more. 

Anyway, its just something to have fun with while at sea. If you want accuracy you have gps - but for the sheer love of marine history we have sextants, compasses, and log lines.

Cheers
