I was looking at the C34 specs. In the "sail plan" portion are 4 dimensions:
I 44'-0" 46'-0"
J 13'-6" 13'-6"
P 38'-6" 40'-6"
E 12'-0" 12'-0"
What do those letters stand for? They are not shown on the brochure.
Thanks.

The first column is for a standard rig and the next is the Tall rig...
J= horizontal dist. from the mast to the forward most jibstay intersepts the deck or jib tack.
P= Mainsail host
E=Mainsail foot..Dist between the aft edge of the mast to the inner edge of the band on the boom.
I= The upper point is the intersection of the mast and the highest jibstay sheeve. The lowest point is the shear line abreast the mast.This is usually a factory supplied distance used for handicapping.
Your sailmaker needs to know these numbers.
