No . . .
They are going to weigh boats.
Hobie, NACRA and Capricorn sails are assumed to be F18 class legal.
There are only 3 brands of boats at this event.
That is not correct. All boats and sails regardless of who built them technically require certification. The inhouse certification is still a work in progress. The NAF18 Class and I assume the Canadian F18 class have been very lenient on this issue and have not required measurement certs at our regattas. The NAF18 fleet has a prescription to cover this but unfortunately only AHPC sent us an agreement, so we (NAF18) really haven't addressed the issue fully.
We really need to tighten things up as a fleet but resistance is significant.
It's also important to note that the NAF18 prescriptions only apply to the US F18 fleet.
