Today I had the pleasure of talking to Gonzalo Tampier, a naval architect in Chile. This is the summary from the meeting.
1- Design the boat firstly from a "steady state" point of view, i.e. design a good hull/sail/keel combination assuming a rigid hull, thus curvature becomes a secondary design concern.
The results of this is that Gonzalo and myself (Roberto) will be working together in the next couple of weeks to design an appropriate hull/keel/sail combination for our purpose (towing an oil boom) so we can have a final design for when we build the final prototype.
2- We talked about the nature of resistance in boats (wave, friction etc) take a look at my previous post for a good intro to naval architecture.
3- We will be sending hull shapes (or main dimensions) so that Gonzalo and his student Javier can analyze them using VPP (velocity prediction program http://en.wikipedia.org/wiki/Velocity_prediction_program) probably using DXF files that can be read by both solidworks and rhino.
It was a very productive meeting and we have another one tomorrow so keep tuned!
