Tom, take a look at 3(a). While you're correct that the word "specification" is in there, and I beg your pardon for my error, a boat doesn't have to meet the specifications to be submitted. Further, as has been demonstrated in past equipment evaluations, the boat that meets the most specs isn't guaranteed selection.
In my line of work, RFPs and specifications have a strict meaning; ISAF seems to use them more loosely.
