I have been working with Carlson hulls for a while, designing my 20
footer I have been squaking about for the last year. I think I have
the final shape of the hull but I still have a couple of questions.
The numbers I have questions about according to the program are as
follows:

Prismatic Coeff = 0.54
Disp. Hull Speed = 5.47 kt.
D/L limited speed = 7.71 kt.

Can anyone explain these numbers in simple terms so even a toothless
old hippie can understand??

Thanks, Scotty
