Up to the PHRF committee. My guess is that they do not think it is a problem with the J/80s.

10. Dry sailing:
a. A boat that does not have a permanent wet slip or does not have anti-fouling
bottom paint, or a boat that has anti-fouling bottom paint but is normally kept out
of the water the owner must have declared on their PHRF certificate DRY sailed.
All other boats will have WET sailed declared on their PHRF certificates. The
PHRF committee will decide whether or not the class’s BASE rating is based on
WET or DRY sailed and will, on a case-by-case basis, adjust the NET rating by +3
or -3 seconds for the boat(s) within the class that are different.
