That hasn't been my experience. Around here the one design fleets see a distinct advantage between dry sailed and wet sailed boats in the same fleet. In fleets where the competition is tight dry sailed is faster.
When it comes to PHRF fleets it is not as critical, but it still makes a difference. When it really becomes noticeable is when one boat starts an "arms race" by getting serious about weight. There is a Catalina 27 in our club who did that; He removed so much weight from his boat that it sat 2" higher in the water than any other C27 in the club, and he dominates them, along with most other boats in his division. Yes he is a good sailor with good crew, but so are many of his competitors. The big difference is the boat is just plain faster on all points of sail.
As long as all your competitors agree to leave the cast iron frying pans and canned food on board you will be fine, but if others take the weight off and you don't, you will be at a serious disadvantage.
