155% on 356...
Abe,I have a 155% on my 356 for a 3 years now (std main). It makes a big difference on light air days. I use it for racing to not loose the sail area to boats with the similar ratings that have the bigger headsails. If you are racing, then I would say get the bigger headsail. If for cruising, then get an ASM. The 155% will increase the weather helm, but I do play with the traveler a lot.I put in a track next to the cockpit, but you can fly the 155% without it. the track helps with light air and getting the right sheeting angles, but in medium air, I just run the sheets back to blocks where the spinnaker blocks are on the arch for the arch. You will need the spinnaker wenches on the side of the cockpit (356). As far as sheeting in the 155%, it goes up to but doesn't touch the spreaders by sheeting outside of both outer shrouds (110% goes between inner and outer).My 356 sails well in very light air when other boats are just turning circles. For racing, it is well worth it. I don't know it it will do what you want since you have a furling main. If you want further info, or more details, e-mail me (sestyles@yahoo.com).Steve
