Kalostyn was designed as the subject matter of a book that I had planned to write called, How to design a boat using SketchUp 3D software.
I created a design that had lots of curves in order to demonstrate how to put these curved forms into a 3D model, and then create and export the the framing and flattened hull panels.
I have yet to write that book!
The design intent was for a hull that would perform reasonably well on low horsepower. I had about 15 hp in mind. The transom is designed to take a long shaft motor.
