yes maxsurf uses nurbs technique so is good for designing most vessels from scratch
but the disadvantage is u dont actually work with data point but control points so if u have an existing design and want to make changes to that i would advise to use NAPA
Yes, Maxsurf is a very good software for design planning and catamaran vessels. Actually, you need the Maxsurf suite of software, ie. : Maxsurf, Hydromax, Hullspeed and Workshop.
