The Naval Architect's Toolbox for the Preliminary Design

Prelimina.com is an online service that will offer a range of tools for naval architects. It is currently work in progress, and each week/month new tools and features are going to be added. Since there are various tools for the basic ship/boat design, this system-agnostic toolbox can offer hydrostatic and hydrodynamic calculation tools for those designs. In addition, Rhino plug-in is in the making. If there is interest, we can also compile the tools as offline plug-ins for other popular design software. Please contact us for any enquieries.
