The Naval Architect's Toolbox for the Preliminary Design 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.


Some calculations execute on user's computer, and some execute on the server. The execution is available for all recent web browsers (i.e. from 2017).
Your browser can execute the tools.
