• Free and Low-Cost CFD Software  
  "Commercial CFD software costs an enormous amount - $25,000 for a one-year lease for a single computer is typical. This site focuses on software with a web presence. However, almost every CFD paper has custom code behind it, which you can sometimes obtain by directly approaching the developer" (Added: 7-Feb-2000 Hits: 3669) | Rate | Visit

• Hull Resistance Calculator  
  Online calculator by Fiona Sinclair based on equations and formulae in "21st Century Multihulls" by Joseph Norwood Jr. The aim is to derive simple mathematical formulae for the design of minimum-resistance hulls. The formulae can be used either for non-planing displacement hulls or for multihull outriggers. It is assumed that the front section has semi-elliptic plan and exponential profile, while the rear section has exponential plan and semi-elliptic profile.
