First of all, thanks for an excellent sonata-site! I have a question about the forestay: how tight/slack should I set it up? My sailing friends reckon it should be much tighter than it is – but I can
Because the shrouds on the Sonata are almost in line with the mast (Not swept back) they provide very little forestay tension. Tension comes from both the Main Sheet and the Backstay. Sonata Sailors get used to the fact that there is a “sag” in the forestay but that does not mean that the boat sails slowly. You just have to get used to it and develop the right technique! I suggest you read Steve Goachers tunig guide:
Good luck and happy Sonata Sailing!
