And have to acquire your own seperate handicap rating with a payed for measurement certificate. You can't you the standard (F16/F18) class handicap number as your boat won't measure in as one. I can already tell you that your handicap number will take an ENORMOUS hit as all the spinnaker area will now be regarded as jib area. For example on the F16 :

Standard sloop F16 Texel = 102, SCHRS = 1.01
Code-0 sloop F16 Texel = 88. SCHRS = 0.831

I don't believe those rating numbers are doable with a Code-0, you have to be 7 to 9 minutes faster around the course per 1 hour race and you are not going to point as high as a normal sloop. Note, that you have to carry this sail in all conditions and so will get the hit even in winds above 8 knots where you really can't carry a headsail this large.

I think we must regarded the code-0 as it was always intended, a specialized light winds headsail that can be sailed above a beam reach. I'm sure Booth is going to drop this sail for the next event that is expected to be above 8 knots of wind. His boat/rig for this Olympics is the sail suit version of a "single-gear race car". It only works on the specific track it was intended for. This is fine for large mono's as they are allowed to change sails while racing, but now of the cat classes allow this and so the overall benefit will be dicey.
