Randy, A PO raised Touche's boom about 6-8 inches. I've never considered that enough to file for a change to my PHRF rating since my main sail extends fully to the design E dimension.
However, your main sounds considerably smaller than design. Is that reflected in your handicap rating? If not, you might explore appealing for a credit. Not sure how your local rating organization handles changes but you could see if you can get a credit if you leave it like it is. I would appeal my rating for a 3-6 second credit if the boat was in my rating area. Some advantages to this. You can keep your existing main while you learn the boat. If you buy a new main, it will cost less. Your crew will appreciate the headroom. Remember, your boat is primarily driven by the head sail. The main sail creates the slot and influences the flow through the slot to provide drive. If you decide to return to design dimensions, just don't exceed your design P and E dimensions and you should be OK. http://www.cncphotoalbum.com/technical/measurements.htm Dennis C.
