The ORC's Superyacht Designer VPP is available for purchase and download on the ORC website. The ORC Superyacht VPP (ORCsy VPP) is a Velocity Prediction Program that forms the core of the ORC SuperYacht Rule (ORCsy).

The software is accompanied by the ORC Manager, an editor utility program for entering and editing measurement data as well as an Offset editor for editing hull offset files. Input data in DXT and OFF file formats can then be used to produce the hydrostatic data and polar diagrams that predict boat speed for full range of wind conditions above 6 knots of true wind speed at the following true wind angles: optimum beat, 52, 60, 75, 90, 110, 120, 135, 150 degrees and optimum run.

The ORCsy VPP Designer's version (DVP) uses the same software used by the ORC Central Rating Office to issue certificates.
The results data includes all the ratings and time allowances shown on certificate, together with a complete set of calculated hydro and aerodynamic data and that defined by the ORCsy rules. The ORCsy DVP is Windows-based software, easy to use, with a user-friendly interface and standard Windows functions.

Any designer may process design data through the VPP to analyze rating effects, and the software is therefore regarded as essential to anyone contemplating an ORCsy design project. The subscription will not give access to existing hull data without the written permission of its designer, while rig, sails and other measurements can be obtained from any copy of an ORCsy Certificate through ORCsy Sailor Services. The annual subscription to the ORCsy DVP is €1200 while the price for current ORC DVP subscribers is €840. Upon receipt of your payment, new subscribers will receive credentials to log on to the DVP Subscribers web page, while credentials of existing subscribers will be renewed. From this DVP page you can download the installation software package and regularly check for updates for one year of both the VPP core and the editing and management interfaces.
