Interpretting the specs....
« on: June 26, 2001, 04:19:19 PM »

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.

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.
