Assuming your hull is hard-chined, I haven't tried it for myself but Freeship or Delftship should allow you to locate the control points of control edges at the exact xyz locations of the corners on your forms. You'll need to create the stem/stern using freeship tools to form a watertight hull, but once this is done hydrostatics should be available.

Another way is to write a text file of the xyz co-ordinates of the chines at the form locations, then import it into freeship.

: I have shaped my own forms to the point i am happy
: with what i see.

: Question is, would one of the kayak design programs out there
: allow me to enter the exact dimensions of each of my forms?

: They all seem to determine form size by changing the hull shape "click
: and drag" style.

: I'd like to enter all my forms sizes and see what the hydrostatics etc are.
