A. Sail material guidelines are intended to encourage the use of sails that are cost efficient and that are aesthetically appropriate for Classic racing.  Classic Yacht Racing Guidelines first published in 2020 remove the prior requirement for paneled construction and allow for ‘molded’ sails.  This change also removes the requirement for ‘woven fabric.’   In the Vintage and Classic divisions, carbon is prohibited (since low stretch sails risk damaging older hulls hardware, and rigs), and only classic, light colored sails are allowed. In the Spirit of Tradition and Modern Classic Divisions, sail materials and colors not restricted.
