Carl wins on this.  From the original brochure, the following specs:
 
Sail Area (100% Foretriangle) 560 SF
I = 45.00'
J = 13.33'
P = 39.12'
E = 13.12'
 
The "E" I noted in an earlier email was listed on the web as the PHRF LIS measurements/ratings.  My own PHRF cert shows an "E" of 13.40'.  I guess I'll be measuring this spring.
 
Let's do the math: if the foretriangle is 1/2*J*P = 260.73 SF, subtract from 560 SF leaving 299.26 SF for the main - in theory.  Therefore, 290 SF seems a mite small, but I would also not interpret 299 as the maximum.  The hard numbers are I, J, P, & E, and that the fixed backstay made of SS Rod Rigging must remain.  If anyone feels that the definition is too loose we can address it as a class, but I haven't heard anyone complain yet that someone has "over-roached".
