As usual I may be the bearer of ill tidings here, but except for the few instances that actually ARE as Mr Polk describes, the typical boatbuilders' practice is to display the hull number or serial number as the 'racing number' on the factory-supplied sails. This is a cute (meaning trite) practice to make owners FEEL like they really have got 'official' racing numbers when in reality most owners, like Mr Chastain, probably aren't the wiser.I would only recommend having such numbers if they are legitimately for racing, in which case you should DEFINITELY have them. Otherwise posers could paint a NASCAR number on their T-Birds or Monte Carlos and it would mean the same thing.JC 2
