Discussion
The fundamental cause of "helm", be it weather or lee, is the relationship of the center of pressure of the sail plan to the center of lateral resistance of the hull. If the center of pressure is astern of the center of lateral resistance, a weather helm, the tendency of the vessel to want to turn into the wind, or to weather-vane, will result.
If the situation is reversed, with the center of pressure forward of the center of resistance of the hull, a "lee" helm will result, which is generally considered undesirable, if not dangerous. Too much of either helm is not good, since it forces the helmsman to hold the rudder deflected to counter it, thus inducing extra drag beyond what a vessel with neutral or minimal helm would experience.
See Sailing Theory and Practice by C.A. Marchaj for a mathematical analysis of the dynamics of weather helm.

Famous quotes containing the word discussion:
“My companion and I, having a minute’s discussion on some point of ancient history, were amused by the attitude which the Indian, who could not tell what we were talking about, assumed. He constituted himself umpire, and, judging by our air and gesture, he very seriously remarked from time to time, “you beat,” or “he beat.””
—Henry David Thoreau (1817–1862)
“The whole land seems aroused to discussion on the province of woman, and I am glad of it. We are willing to bear the brunt of the storm, if we can only be the means of making a break in that wall of public opinion which lies right in the way of woman’s rights, true dignity, honor and usefulness.”
—Angelina Grimké (1805–1879)
“There are answers which, in turning away wrath, only send it to the other end of the room, and to have a discussion coolly waived when you feel that justice is all on your own side is even more exasperating in marriage than in philosophy.”
—George Eliot [Mary Ann (or Marian)
