Sorry I messed up by not letting people know the new scoring standards. I am learning myself. If you haven't already watch Jim Teeter's video in link below:

TOT is the standard for scoring using the eZ. I did a quick query and couldn't find anyone using TOD with eZ today. Might get Kett to provide the reasons why.

Please be aware that a few boats are getting two eZ CERTS. One for a sail plan using a genoa (larger head sail) the second using a jib (smaller head sail with light air material). I will attempt to explain the reasons why. See the example below:

CERT 1 called Genoa has a SPIN PHRF rating of 126.8 with a head sail of 228.2 ft².
CERT 2 called Jib has a SPIN PHRF rating of 135.3 with a head sail of 170.7 ft².

By using a smaller head sail plan with light sail material, there is a rating benefit of 8.5 seconds per mile based on the VPP performance curve model.

As a former One Design Class President, I am encouraging our sailors to stick to the official One Design plan per RRS 78.1 which says while a boat is racing, her owner and any other person in charge shall ensure that the boat is maintained to comply with her class rules and that her measurement or rating certificate, if any, remains valid. In addition, the boat shall also comply at other times specified in the class rules, the notice of race or the sailing instructions. The J/30 Class rules say you must carry a genoa at 163% of J.

Per NOYC WNR NOR, rule 2, the regatta will be governed by the rules as defined in the 2025-2028 Racing Rules of Sailing, including US Sailing prescriptions, the Gulf Yachting Association handicap bylaws and class rules, this notice, the NOYC General Sailing Instructions, and any posted notice to competitors.

So be careful with using multiple CERTs aligned with the goals of class rules.
