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.
