It is interesting that you mention sailing F16 single-handed boats head-to-head with the F17! We have done this in the Catfight for the last 4 years because all the single-handed boats start together. I don't think there would be any objection to having them sail and be scored in the same class and I think it would be good for the F16 Uni sailors to have a (larger) fleet to play in. It would be up to the skipper to decide if he wanted to sail with the F17s and register that way for scoring. I am pretty sure that the double-handed F-16 would be scored in the Low Portsmouth fleet. Regardless of whether the boat is the same speed or not, 4 hands against 2 hands is just not always fair, IMHO.

The alternative is to sail Portsmouth fleet and be scored on handicap. CRAM has a High Portsmouth and Low Portsmouth class which are scored separately. This last weekend, the Low Portsmouth class included NACRA 20 and A-Class and the Low Portsmouth included H-18, H-17 and H-16. One design fleets were F-18 and NACRA 17.
