Since not all 135's are equal and since a little research will get you a
lot of knowledge...I know, it's easier to type an email than getting the
answer yourself
The following formulas will give you approximately areas for:
Mainsail = (P x E) / 2 (add 10% for racing mains)
155% Genoa = (( J x I ) / 2) x 1.65
135% Genoa = (( J x I ) / 2) x 1.44
100% Jib = ( I x J ) / 2
Racing Symmetrical Spinnaker = 1.8 x J x I
Racing Asymmetrical Spinnaker = 1.8 x J x I
Cruising Asymmetrical Spinnaker = 1.65 x J x I
DEFINITIONS
"P" is the luff length of the mainsail, measured along the aft face of
the mast from the top of the boom to the highest point that the mainsail
can be hoisted or black band.
"E" is the foot length of the mainsail, measured along the boom from the
aft face of the mast to the outermost point on the boom to which the main
can be pulled or to the black band.
"I" is measured along the front of mast from the genoa halyard to the
main deck. The main deck is where the deck would be if there were no
deckhouse.
"J" is the base of the foretriangle measured along the deck from the
headstay pin to the front of the mast.
"JSP" is the length of the spinnaker pole or the distance from the
forward end of the bowsprit (fully extended) to the front face of the
mast.
"ISP" is measured form the highest spinnaker halyard to the deck.
"PY" and "EY" are, respectively the luff length and foot length of the
mizzen of a yawl or ketch measured in the same way as for the mainsail.
"IY" is the measurement from the staysail halyard to the deck.
"JY" is the measurement from the staysail stay to the front face of the
mast.
"LP" is the shortest distance between the clew and the luff of the genoa.

Speaking of PRHF I am filling out the form for my newly purchased 2000
C320
with a 135% genny. Does anyone know the LP measurement for her, with the
135%?
Thanks in advance for the help
