Rob, thank you for jumping in on this...your explanation is very helpful; can you elaborate on how those design weights and specs affect the normally used ratios; SA to displacement; displacement to length, and Ball-Displacement? Are the "design" numbers used or are the boats weighed? Also, not of importance, but I would love to know, historically, which boats, or lines you considered as your competition? Lastly, thank you for for the 37 it is as beautiful today as when it left your factory in 1985....(as was my 25, 29, and 33)...

Then create a hull shape that has that exact volume. Then the rest of the design follows suit. Meanwhile, if a company wants to sell any of these, some specs need to be available so they have something to explain. So, the predicted displacement number gets set. After that the details of the design are completed, the structure is planned, the number of coats of varnish are decided, and anywhere along this path you can see that the original predicted displacement is totally lost . . . but it’s still out there as the published number . . . When the first boat is launched, we’re now many months away from that original prediction, and back then – it’s the first indication of what the boat actually weighs . . . I feel that much of our success at C&C was the ability to predict a finished weight and have the boat come out close to that number. Our competitors often went to the latest hot designer, got a nice design, that was maybe even a lot lighter than we were doing. Aha – should be a world beater – right ? But . . . . they didn’t build a boat lighter than we did and more likely a bit heavier. So – we had a C&C relatively heavy for it’s size and a competitor’s boat which was designed to be light, but actually wasn’t. The C&C had a sailplan and stability to match it’s weight, but the other guys had a boat that was considerably overweight and probably underpowered as a result. As the years went by, I had a more and more sophisticated ability, and understanding of what we were doing so I could do a design, see it built, and have the design and actual be closer and closer. I really felt (feel) that we outsmarted the rest of the world for a long time. Of course in our computer age, it’s much easier to design a boat now. You can do the whole design, do a weight study, and then change the hull shape, keel weight, or sailplan at the very last minute to match the weight.
