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 formed part of the International Paint Poole Regatta with 27 boats racing over two classes. With a significant local entry expected for the 2025 event, exciting racing is expected in the central Solent.

This year's National Championships returns to the Solent to be hosted by The Royal Southern Yacht Club, Hamble over the weekend 19th-20th July. Having successfully hosted the X-Yachts Solent Cup in 2024, using VPRS, the Royal Southern Yacht Club is uniquely positioned to host this year's event at the height of summer.

A packed weekend is planned with three races on Saturday followed by a longer distance race on Sunday. Double points will be awarded for Sundays' race adding an exciting competitive edge. Off the water a VPRS Sailors Supper at the Royal Southern Yacht Club on Saturday evening provides an opportunity for sailors to relax and socialise.

Sunday's race will be followed by the event prize giving, courtesy of Stoneways Marine Insurance, leaving time to return to home berths.

Stoneways own Yacht Manager; George Beevor due to be competing in his own Hamble based, Sparkman & Stephens 35 "Ugly Duckling", is looking forward to competing:

"Our crew are excited to be racing at the Stoneways VPRS Nationals this year, on what are our home waters coupled with legendary hospitality provided by the Royal Southern."

The Notice of Race and Entry is now open here.
