Hi Dennis, Before ordering the new headstay, I would experiment by adding a toggle to the bottom of the headstay. A toggle at the top sounds like someone reheaded the rod and made it too short? Is there a toggle on the backstay that you can remove and use on the headstay? Setup your rig, go sailing. See if it works how you want, then order the new stay to that length.
I have read that 1 degree of mast rake is a boat designer's target. Sailmakers like more rake, especially for light air. Some tuning guides (J35) suggest adding a 2" toggle to the headstay when racing in less than 15 knots and removing that when true wind is above. Some of this is driven by weather helm. You know your boat best.

I think a ½” of movement at the base of the mast should give you at least 5” at the masthead.

Sent: Friday, September 07, 2012 6:14 PM To: Cn Clist Subject: Stus-List Mast rake adjustment OK, check my math and thinking on this one. I want to increase the rake in Touche's mast. I made some changes in the rig a few months ago which brought the masthead forward so the plumb from the masthead is only about 6 inches aft of the gooseneck. It used to be 9-10 inches to get 1 degree of rake. The foretriangle is close to a right triangle. I=44' and J = 14.5'. If I add the 6 inches to J (for the plumb drop from the masthead), I get a right triangle with sides of 44.0 and 15.0 and a hypotenuse of 46.487 (the forestay). So, if I want to move the masthead aft another 6 inches, I end up with a triangle of 44.0, 15.5 and 46.650. The difference in the lengths of the hypotenuses (hypoteni?) is 0.163 or about 2 inches. By my thinking, I need a new forestay about 2 inches longer than the existing one. There's more to the story than this, like it's really 5 inches each for the plumb and rake increase and I'm removing an extra toggle from the top but the math and method should be right. Am I right?
