OK, right this minute I''m having favorable throughts about the cape code catboat design. It has been noted that the centerboard does not necessarily provide enough stability (at least not as much as would be desirable).
This makes me wonder if one could construct a large centerboard (long from front to back) with a ballast bullet attached to the tip of the centerboard and some kind of simple ratchetting winch mechanism to raise and lower it.
If such a thing could work, could you not gain the added stability similar to that of a ballasted fin but still be able to retract it for shallower waters?
Just think''n is all...
