Craig... Every other form of handicap racing puts the responsibility on the owner to get their damn boat measured for the race. Only beach catamran world tolerates a bunch of beach bums who show up on the day of the race with a boat and expect to race without prior paperwork or registration.

Yes, it is more trouble to get your changes measured before you go racing. ... IMO... since you made the changes.... you own the responsibility to the fleet to get a fair rating.

There are people who measure and it costs you a fee to have your boat done. You also have the option of being a corinthian sailor and measure your own gear and calculate your rating.. Corinthian Sailing runs on the honor system.

Still, It is the OWNERS responsibility... not the OA or the person running the US ratings service.. At best... his job is to hunt down the owner with the measured changes and a one of a kind rating and make sure a copy gets sent to ISAF SCHRS or Dutch Texel.
