same as..
I kind agree with Russ. I have a 1973 O23 and a lot of times I forget to even put it down, but also as said below, there is a difference for sure. How big of a difference, well, since I am out to just have fun (no racing or anything like that), I could care less. Because a great deal on Ebay, I just purchased a 1972 O22 and that model has just the fixed portion of the keel, no swing board at all. I do relize the 22 is close to 1000 pounds lighter, but wondering if the swing board makes such a difference, whe where they not put on the 22's?
