Wojtek,
A great place to start would be to have a look at the class rules.

You should be able to get the basic measurements from there. The jib clew
typically has a clew board with three holes in it like the 49er. The location
of the clewboard is critical and it may be better to visit someone in your
area that has a suit of sails to determine the actual location and angle.
Mast bend can vary a bit depending on whether the builder chose to sand and
refinish the mast before rigging it. It may be best to get your mast, decide
if you're going to sand and put your own finish on it, and then test it with
the mast track on. Attached is an xl spreadsheet which will provide a good
starting point.
We vary/change our mast a rake a fair amount--depending on the wind/wave
conditions (there is no set rule). Our kites are affected a great deal by
mast
rake. Generally we are raking aft in heavy air for the typical benefits (it
loosens the caps and lowers, loosens the jib leech, and tightens the kite
luff--driving the fullness forward). We do have a rather standard rake
starting
point buy you'd need you boat finished to make that work (it is a
measurement from the transom bar top to the tip of the mast with the cap
pressure off.
I'll dig that number out for you)
Best regards,
Bram

Hi,
I'm trying to design myself some sails. I dont have the boat built yet and
the rig is on it's way. I need some dimensions. Like luff, foot, forestay
lengths. Mast rake and mast bend for the forte spar. Clew location for jib.
The E, P, J. Any of this information would be greatly appreciated.
cheers,
Wojtek
