This pisture helps some, but can you take some from the aft end as well. The hull shape and centerboards are somewhat similar to a scaled down tornado. What is the actual length and beam of the boat. You could post this on the tornadocat yahoo group and see if Geoff Dobbs could help if this boat does have SCoC ID on the hulls. Craigslist is actually a good place to look for sails, masts and misc parts.
