Boat Speed
If your speed log is disabled, you can calculate the boat's speed by determining the time it takes for a wood chip or other floating object to pass from the bow to the stern. If you want to retrieve the object, attach a string to it.

Boat Speed = (60 (sec/min) * 60 (min/hr) * length of boat in feet) /
( 6076.1 (feet/nautical mile)* seconds for chip to pass)
How long is your boat in feet?
How long does it take for a light object to reach the end of the boat in seconds?
 

Sail Area Displacement Ratio
