SpringSharp 2.1

SpringSharp allows you to design "what-if" and "never built" warships between 1850 and 1950 using little more than the specifications in books like Janes Fighting Ships, Conway's All the World's Fighting Ships etc.
It applies parametric formulas as used by professional Naval Architects (Mumford, Parsons, Holtrop & Mennen etc) as well as empirical data based on research on ships (Liners & Warships) of the period to give a soundly grounded and scientific basis to your designs.
SpringSharp produces a written report in far more detail than the above resources.
