Forces on sails to stay within the limitations of a craft's stability and power requirements, which are functions of hull (for boats) or chassis (for land craft) design. Sails derive power from wind that varies in time and with height above the surface. In order to do so, they are designed to adjust to the wind force for various points of sail. Both their design and method for control include means to match their lift and drag capabilities to the available apparent wind, by changing surface area, angle of attack, and curvature. Wind speed increases with height above the surface; at the same
San Diego Sails (A "crowd" of 1,670 showed up for San Diego's third and last home game, against the San Antonio Spurs.) Goldberg soon learned San Diego was to be shut out of the pending ABA-NBA merger.
