Benny - I appreciate your engineering approach to the subject question but the waterline wouldn't be the fulcrum, would it? When we are under sail, the fulcrum is below the waterline. I'm too lazy to do a complete analysis but whatever the point of rotation when we heel would be the fulcrum. If the waterline were to ace as the fulcrum, the whole hull on the windward side of the boat would lift out of the water with the hull on the lee side still at the waterline.As far as the horizontal force on the boat, the centroid of the sailplan, which as we know can exceed 200 square feet, is located approximately 12' above the waterline when under full sail. The study of statics tells us that if we multiply the average force exerted on the sailplan by the moment arm, which is approximately 12' in this case, a 1 lb. force exerted on the centroid yields 2400 ft/lbs. We all know that a 12 knot wind exerts a great deal more than 1 lb. of force. The point I'm trying to make is that when we are under sail in a 12 knot wind, the horizontal force exerted on our boats far exceeds 2400 ft/lbs. If there is no horizontal force acting on the 200 lb. man, the resistance to his weight is straight down. A man would need a tremendous amount of horizontal force exerted on him to equal a boat under sail. Assuming no horizontal force, he would need to be suspended 12' from the centerline of the boat (200 lb. x 12') to equal a fully rigged boat with 1 lb. of force exerted upon it by the wind.I'm not very skilled as a sailor or as an engineer for that matter. I'm trying to apply stuff I learned in a statics class 35 years ago. I'm not sure it transfers to naval architecture.
