Rex, are you really on a Nacra F18? I'm sure you've seen the leap forward that designs took in about 2005 that has carried through to today... volume has increased dramatically with each iteration and the power in the rig has matched pace. Your team weight on a Tiger would yield very different results than your weight on designs that have come out this year or even last. The incremental improvements are small year-to-year, but cumulatively, they're remarkable. The good part of that is that you don't need a brand new boat to take advantage of increased volume and power for your weight range. Note that teams around 150kg did very well on Tigers at F18 Worlds (IMO).

Que the ratings discussion... yes, Virginia, the rating has stayed the same as the boat has gotten faster over time. Not my fault, and I don't race Portsmouth.
