Use with caution. Anyone with any corrections should post to the discussion page or e-mail me.

Definitions:

I = Height of headstay termination above the sheer line.
J
= Distance between the headstay termination at the deck and the front of the mast at the sheer line.
P
= Distance between black bands on the mast, or the maximum luff length of the main.
E
= Distance between black bands on the boom, or the maximum foot length of the main.
PY & EY
are similar to P & E, but indicate mizzen dimensions.


Sail Area Calculations

(Again, these formulas will give approximate sail area calculations.)

Mainsail Area = P x E / 2.
Headsail Area = ( Luff x LP ) / 2. ( LP is the shortest distance between the clew and the luff ).
Approx. 150% Genoa Area = ( 1.5 x J x I ) / 2.
Approx. 135% Genoa Area = ( 1.35 x J x I ) / 2
.
100% Foretriangle = ( I x J ) / 2.
Approx. Spinnaker Area = 1.8 x J x I.
