Absolutely, the ratings need to be the same. This is a class foundation. However, the sail configuration needs to handicap single and double handed accurately.

I race primarily uni but have done a couple with inexperienced crew. The jib effect is valid. Much more power and greater righting moment in tandem with the newer hull designs more than offset the additional crew weight.

I am opposed to structural design modifications to optimize uni configuration; ie. smaller hulls because the boat will loose its 1 or 2 up flexibility which is a differentiating quality of the class that also must be preserved. That leaves us with sail development.

I agree with Wayne that simply dropping the jib may not be a valid equalizer either. It may have been with the early generation hulls. Whatever the case, not enough racing/development has been done with top racers using a uni-cut main to justify even exploring adding a small jib with reduced main.

Ironically, I believe the manufacturers would sell more boats and sails if sail development (and rules if needed) allow unis to be more competitive at the regional/national/world events.
