Dwight,
"I" is the deck to masthead measurement, i.e. the vertical side of the
triangle. The forestay is the hypotenuse.
I'm trying to return the rig configuration to where it was before the
adjustments I made. I did have 10 inches at the gooseneck. Now just 5. Like
I said, there's more to the story.

>Sorry Dennis, on reading again now I see
what you are doing…got confused when you said the new hypotenuse was
46.487, compared to what it was at 44…actually I don’t see why you
need to change the forestay at all, the head stay should have enough adjustment
in it…does it not have a turnbuckle at the bow that you could lengthen a
bit

>And another besides, why are you doing it…seems
from what I have read Touche has consistently been at or near the top…trying
for better performance or less weather helm

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.
