The only thing Rhino was used for was the half hull (using Rhinomarine). Rhino is a great surface modeller. Honestly though, SolidWorks does just as well or better in some areas of surface modeling. The area SolidWorks doesn't do well is in laying out the hull. In fact, I think the problem is that it's 'too good' and doesn't allow the amount of global control that Rhino does. There is no 'net' control on SolidWorks surfaces. The closest thing to that currently is Freeform, but that actually is too precise for it to be useful. If SW would introduce surface net controls, I'd be done with Rhino.
Hands down, SolidWorks (and others like ProE or Inventor) are much better for handling the modeling details. Whenever possible, working with true solids is always better than modeling in surfaces. And most manufacturers these days offer their products as 3D solids. All the running gear on this boat uses models from Harken and Wichard.
