(a) A sailing vessel that operates on protected waters must be designed to satisfy the following equation:
Where—
B = the distance between hull centerlines in meters (feet).
As = the maximum sail area in square meters (square feet).
Hc = the height of the center of effort of the sail area above the deck, in meters (feet).
W = the total displacement of the vessel, in kilograms (pounds).
X = 4.88 kilograms/square meter (1.0 pounds/square foot).
(b) A sailing vessel that operates on partially protected or exposed waters must be designed to satisfy the following equation:
Where—
B = the distance between hull centerlines in meters (feet).
As = the maximum sail area in square meters (square feet).
Hc = the height of the center of effort of the sail area above the deck, in meters (feet).
W = the total displacement of the vessel, in kilograms (pounds).
X = 7.32 kilograms/square meter (1.5 pounds/square foot).
