Additional info: It looks as though all individual boats meeting formula rules are rated the same as the "general" formula handicap - so we there must be some mechanism in place to evolve each formula handicap as a group.

The only remaining dilemma is the Uni vs. Double for F16, which is not applicable to the other formula classes. Should the Uni and Double be rated the same for open class racing? Texel rates them differently, as well - correct?

Portsmouth has Uni rated slower - would you be upset if you were doublehanding your F16 at a large Open class event, beat a Uni F16 on elapsed time but the Uni F16 corrected over you? This is a mixture of class and open rules.....
