I'm thinking of adding a cruising spinnaker (asymmetric, poleless) to my C&C Landfall 35 that I often sail single-handed in Long Island Sound. I understand that I will need the sail, dousing sock, ATN tacker and new sheets. I know that all the major sailmakers market this product, is it worth the name brand price differential? Any suggestions about sail makers, things to avoid or other advice? Is the sail really a good addition for the light-air LIS days? Thanks
