(a) A sailing vessel that operates on protected waters must be designed to satisfy the following equation:[GRAPHIC] [TIFF OMITTED] TR10JA96.007 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:[GRAPHIC] [TIFF OMITTED] TR10JA96.008 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). [CGD 79-023, 48 FR 51017, Nov. 4, 1983, as amended by CGD 83-005, 51 FR 924, Jan. 9, 1986; CGD 85-080, 61 FR 944, Jan. 10, 1996]
