My reference is to the potential for crew weights to drop in the f16 if that class was made Olympic.

If you are sailing anything other than Olympic level then you will be more than ok and can continue to enjoy your boat as you have been.

But the Olympics is a different game, laser sailors stress about 1kg weight differences etc. And at that level it makes a difference.

As for the 2010 USA F18 nats, we borrowed a boat and it was heavier than min weight. Our crew weight was just over min, 154kg I think. We were beaten in a light air event by a lighter team..
