YRA of Long Island Sound gives the J-30 a base rating of 141 then takes 3 seconds each for the spinn pole and oversize genoa to get a rating of 135. This includes a 1260 lb weight limit, no sail cloth limitations or other OD specific regulations.
Yralis.org also lists a J-30 ODR with a 1400 lb weight limit, which probably requires all class gear and sail restrictions, but I am not positive about that.
