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?
