The USPN number of 64 is a good upper boundery as this forces RC's to take us up in the low PN fleets. If they don't then they have to take out of the low PN fleet the following boats as well :
A-cat (65)
nacra 18 sq. (67)
Hobie 20's (64.9)
nacra 5.8 (66)
Nacra 6.0 orginals (64,4)
I17R (66.7)
Prindle 19 (66.4)
Prindle 19 MX (64.4)
and All supercats 19 and 20's (66.5 - 64.4) including Bill supercharged SC20
No RC is going to do THAT !
Right now RC's can lay the threshold rig at 66,9 (=our rating) and throw us in with the H14's without an serious problems to othe 18, 19 and 20 foot designs. It is a smart policy to change that and make it very problematic for them to throw us out on some arbitrary criterium.
