I have four current projects in the Performance section.
First is my lagrangian CFD code. I began the theory for this at Berkeley. I recently rewrote the project from scratch, and am working on ways to improve the stability.
Secondly, I am working on a boundary integral formulation for the potential flow around sailboats. I will most likely use a linearized free-surface.
Third, I already have my Michell's theory in spreadsheet form (and it is fast). I hope to incorporate this with my yacht design system.
Lastly, once I am able to incorporate one or more hydrodynamic tools, I will pair this with aerodynamic theory to produce a generic VPP.

The structural design of a ship is the area which I have the least experience in writing software for.
I have made a 3d FEM code, as well as a 3d Direct Stiffness Method - except not for ships.
My current work is to make a generic spreadsheet for the scantling rules. Once I finish the scantling rurles, I will start on importing the more computational routines for use in ships.

I initially wrote a hydrostatics program in Excel for my first design ever (YP design). I did this because when I made a small change in the hull shape, I wanted to immidiately know the effects on center of buoyancy. I was also able to "balance" CG and CB automatically.
Since then, I wrote another spreadsheet for a specific sailboat, but have now made my spreadsheet for sailboats in general.
The problem with it is:
1) it's ugly
2) it's hard to use
3) there is no "help"
Well, I'm probably going to redo the spreadsheet, and then rewrite the program in another language.
