You might download it and try it. According to the web site, the trial version is fully functional and free, with no time limit, but a restriction on the number of file saves.

The program's forte is curves and 3D surfaces. It was originally an AutoCAD plug-in and the command language is similar. To put it in some kind of context, here is link to a hull design software survey on the Boat Design forum.

http://pkboatplans.com/files/Rhino_40sqm_Hull.pdfIt is not the be-all and end-all. It is a useful tool if you like 3D. I have had parts CNC machined from emailed Rhino3D files, but I have only done it twice so far. It worked fine.
Finally, search YouTube.com for Rhino3D tutorials and videos. There are several on hulls, boats, development from hulls, creating sections, lines & buttocks from Rhino3D hulls, etc. Also, the ORCA3D web site has a 40 minute video about their Rhino plug-in for hull design. Expensive unless you are a student, but impressive.
