Thanks Bill As per rule 5.8.2.1 the headstay length is less than or equal to 35ft10.5in to the deck / plate Therefore a 35'6" eye to eye dimension as stipulated in the specs page in the info tab is within the rules
Thanks

I measured the distance this morning from the center of the bottom eye to the measuring point (as per class rules) and it is 3 1/2 inches. This gives me a 35ft 9.5in total headstay length (which is 1 inch shy of the rules max length)
With uppers @42 and lowers @42, I measured the mast rake from masthead to boom to be 15 inches The true test will be under sail to see the mainsail shape / cut with the mast's prebend....I will adjust the lowers accordingly

Taras - you really want to get that extra inch out and make the headstay the max allowable length. Shortening the headstay is ok for heavy air, but you want the full extension of the mast without pressure from the backstay raking back the top of the mast for lighter conditions. I remove one side of the backstay from the transom just to make sure it is loose when setting up the uppers and lowers.
