I am writing this proposal to be presented to the class to amend an existing class rules for the Inter 20. I propose that rule number 4.6 be changed so that a self-tacking jib system may be installed. It may be a Performance Catamaran original or of the owners design. <br>The new system on the Nacra F18 should be an easy retrofit. A new jib would have to be designed to work with the self-tacking system. I propose that the new design jib be made from Mylar or Pentex for greater life. <br>I would also propose a change of allowed materials for trap wires. I suggest that a non-metallic material be allowed. There is a safety concern with the use of metallic trap lines. A non-metallic material could be easily cut in an emergency situation. <br> Any comments, suggestions or additions?<br><br>
