Just got the latest copy of SCA, and low and behold, "Miss T" is gracing the
cover. Aside from the gorgeous boat, gorgeous setting, etc..... What stands
out is she does have "a lot" of mast rake!

So how much is "a lot". Using the beach as a horizontal reference, and the
lighthouse as a vertical reference, and realizing the view is from about 20
to 30 degrees forward of the starboard beam, I'm measuring about 2 to 3
degrees of mast rake as viewed.....which is more like 3 or 4 degrees if
viewed directly from the beam (spreaders nearly in line with the mast). This
also assumes she was sitting approximately level at the exact moment John
snapped the picture. Granted, this is all very crude....but what else do we
have?

Some of the more enlightened math whizzes may want to check my calculations,
but to get that type of mast rake, assuming P (length of luff of the
mainsail) is 19', then each degree of mast rake would equal about 4" of
distance measured out from the mast at the boom. So if one wanted to get 3
or 4 degrees of mast rake, you could start by measuring off 12 to 16 inches
out on the boom....then level the boat fore and aft and rake the mast until
a plumb bob from the main halyard reached that range. Use that as a starting
point and rake up or down from there?

I think 12 inches would indeed be "a lot" of mast rake!
