"For the development of the Leopard 46 and 40 Powercat’s we made extensive use of the Orca3D software with the CFD extension. This has proven to us to be a very powerful package which gave accurate predictions allowing refinements to the designs which otherwise would not have been possible in …

“Orca3D is used extensively right from the first hull sketch, to monitor and optimise displacement, hull coefficients and areas curves. We use Orca3D’s Holtrop analysis to calculate resistance and determine engine power and optimum speed range. We have found excellent correlation between Orca3D’s Holtrop results, tank testing and deployment feedback …
