Sheeting Sails
No sail shall be sheeted over or through any device that exerts outward pressure on a sheet or clew of a sail at a point from which, with the boat upright, a vertical line would fall outside the hull or deck, except: (a) a headsail clew may be connected (as defined in The Equipment Rules of Sailing) to a whisker pole, provided that a spinnaker is not set; (b) any sail may be sheeted to or led above a boom that is regularly used for a sail and is permanently attached to the mast from which the head of the sail is set; (c) a headsail may be sheeted to its own boom that requires no adjustment when tacking; and (d) the boom of a sail may be sheeted to a bumkin.
