Very nifty idea to have a lash-on subframe. I guess the gaff halyard also tensions the forestay. That polyester fibre material, was it sown or heat-seam hemmed? Kind regards.
luff in mainsail is too long and needs some darts cut in it. La randa ha la balumina troppo lunga e ha bisogno di alcuni tagli a freccia per essere ridotta per una migliore forma della vela. Bel progetto !
