The location of the pivot point shall be such as to provide a balanced design. 8.1 Stays and shrouds shall be attached to the deck with only adjustments for tuning permitted. No provision for adjustment of stays and shrouds by remote control means shall be permitted. Only the main and jib sheets may be adjusted under sail. Jib trim will be allowed.
All dimensions listed below are maximums.
During measurement the sail edges shall be tensioned sufficiently to remove wrinkles. Mast and booms shall not be positioned so as to restrict the proper measurement of the sails. Eyelets in the corners of the sails shall be used to define a straight line for the use in measurement and the measurement shall be taken along a line through the center of these points from fabric edge to fabric edge. If no eyelets have been installed the normal position of the eyelet center shall be simulated. 9.2 Roach and rounded foot measurements shall be from a straight line between the centers of the eyelet locations to the edge of the sail fabric, measured perpendicular to the straight line at the point of maximum departure from the straight line.
