Proved through testing and extensive use over the last 14 years, VPRS offers yacht clubs a single system which is easy to use and gives accurate ratings across a vast range of yacht types – including sportsboats – based only upon measurement data.

The data is used to configure a Velocity Prediction Program (VPP) which predicts the boat's speed for a range of wind speeds and directions. Then it calculates a Time Correction Coefficient (TCC) from these, which is used to correct elapsed times in a race.

Best of all, we provide a fast and friendly service at an annual charge of just £30 for any boat—and we will help you to gather the data you need to get a rating certificate.

Originally developed for PYRA in 2009, VPRS is used by all the major clubs in Poole Harbour as well as clubs in Chichester Harbour, the Solent, Weymouth, Plymouth, the Isle of Man and Ireland. We also have keen users Brazil and in the Mediterranean.

The Stoneways VPRS Championship 2024, which formed part of the International Paint Poole Regatta was a great event with mostly close matched racing in various conditions, testing every crew's skill and adaptability. A huge vote of thanks is owed to the combined yacht clubs of Poole for a fantastically organised race weekend and to all competitors who joined in and made the event what it was. You can read all about it here in the regatta report from our partners, Stoneways Marine.

Right now we're in the process of re-setting the web site for 2025, moving last year's certificates to the archive and implementing a few small changes to the VPP software. Hopefully we'll be ready to run 2025 certificates within a few weeks. There will be a price rise this year: the rising cost of living is getting to us here in VPRS too! But the only change is to the annual membership fee, which is going up to £30, which I hope you will agree is still very good value for money.
