With all the sheets trimmed flat aft, and every rope that helps extend the sails hauled taut. Hauled as close to the wind as the sails will admit without shaking their luffs. When a square-rigged ship is close-hauled she is about from five to six points off the wind. A fore-and-aft schooner, with everything nicely trimmed for racing, will lie within four and a half points of the wind ; a cutter within four and a quarter points. This, of course, supposes the water to be smooth and the wind of what is known as "whole sail strength." In rough water a vessel cannot be sailed so close.
