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
This ratio indicates how fast the boat is in light wind. The higher the number the faster the boat.
10-15Cruiser
16-20Cruiser-Racer
21-24Racer
> 24Performance Racer

Sail Area Displacement Ratio = Sail Area / ( Displacement Volume )2/3
Displacement Volume in Cubic Feet = Weight in Pounds / 64
