Theory
Nearly all methods that increase resistance to sideways movement also cause heeling, the leaning produced by the imbalance of the forces on the sails, high above the waterline, and the sideways resistance, generated by the centerboard or other foil below the waterline. The resulting torque causes the hull to heel until the buoyancy of the hull provides sufficient torque to balance the heeling force. The limited buoyancy of the hull therefore limits the amount of force that the sail can effectively produce.
One solution to dealing with this limit is to bring the forces generated by the sail and the underwater foil into alignment, canceling as much of the torque as possible and thus reducing the amount of heeling. Two approaches to this have surfaced one being the inclined rig, and the other the Bruce foil.

Famous quotes containing the word theory:
“The weakness of the man who, when his theory works out into a flagrant contradiction of the facts, concludes “So much the worse for the facts: let them be altered,” instead of “So much the worse for my theory.””
—George Bernard Shaw (1856–1950)
“... the first reason for psychology’s failure to understand what people are and how they act, is that clinicians and psychiatrists, who are generally the theoreticians on these matters, have essentially made up myths without any evidence to support them; the second reason for psychology’s failure is that personality theory has looked for inner traits when it should have been looking for social context.”
—Naomi Weisstein (b. 1939)
“every subjective phenomenon is essentially connected with a single point of view, and it seems inevitable that an objective, physical theory will abandon that point of view.”
—Thomas Nagel (b. 1938)
