In general, the best people to consult about a boats handling are those who run the same type of boat. This concept boat is really a very clean version of a simplified hull of revolution, so should handle very similar to those boats, but lack any sail induced roll. I read somewhere that the Permit class was originally intended to be sans sail, but they found it too much of a compromise and settled on a much smaller sail than the preceding Skipjack class.
Unusual subjects like a K-class are a bit more tricky- not many people have built those, bu there are one or two knocking about out there, albeit at larger scales.
Another thing to check is information on the fullsize boats handling. Chances are, a model will share some of that boats vices.
One thing we can't scale down are water molecules, and unfortunately that can sometimes pose a problem with control surfaces, especially as the scale of model gets smaller. To get the kind of response the builder is hoping for, it is sometimes (but not always) necessary to sacrifice a little scale fidelity and increase the size of the control surfaces.
