C.7.8 Cunningham lines for both the jib and the main may be used. Line loops (including thimbles or rings of any material) or knots may be added to any part of the line to provide additional purchase. The main Cunningham may be led and adjusted on the Centerboard Cap as well as the mast provided that Cunningham lines shall use only the fittings supplied by the manufacturer. A small Cleat maybe added to the deck of the boat to allow cleating of the Jib Cunningham only. This cleat shall not have any moving parts and shall be mounted no more than 4 inches off the centerline of the deck, and no more than 8 inches from the forward most piece of the splash guard.
