For who is interested: I made a small piece of open office (or excell) code that allows you to use the cross curve data generated by Freeship and generate the seakayaker stability curves, or any other curves with different fixed kayak, paddler and cargo heights. It is available for whoever wants it, but do not expect slick software.

The stability graphs for my new design are posted below. Not to unstable. Looking at the seakayaker reviews it is even better than the similar sized kayak pro Marlin and on par with the Epic 18 that was one of the boats that fueled the design.
