BD has special draft requirements, as does Gardiner's plan to sail in the Chesepeake, and both could be nonoptimal with low-draft beam-mounted rudders. Without enough foil in the water, it's easy to go from laminar to non-laminar flow, and then the foils become a lot less effective. But such is the challenge with a 48' boat designed to sail in 3' water, and yet somehow be expected to hit 20 knots (by observers, not by the owner).
Just as important, rudders on the beam would permit simple tiller extensions all the way to the cockpit, which is something I'd definitely like to try. It's a simple system that wouldn't care one way or the other if the boat were folded or unfolded, won't stretch out of shape, and will be more fun than using a wheel. At least for me -- I much prefer tillers.
