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 £25 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.

Returning for 2023 with a bigger and better event than ever before, The Stoneways Marine VPRS National Championship will take place at The Cowes Corinthian Yacht Club on the Isle of Wight this June. Make sure to mark your calendar to avoid missing out on an action-packed weekend of close competition on the water, followed by friendly post-racing socials with fellow VPRS sailors in the home of British yacht racing.

Stoneways Marine, the friendly face of yacht and marine trade insurance established in 2020, are delighted to continue sponsorship of the VPRS class and the 2023 Championship. Proud to deliver the highest levels of service, care and expertise, Stoneways provide high quality marine insurance solutions. They are often able to provide comprehensive cover, even when others cannot.

The Schedule

Two VPRS fleets are set to race for the 2023 VPRS national Championships, to ensure closely fought racing on the water.

Three short races (ranging from 1 to 1.5 hours per time) will be run on Saturday 10th June, followed by one long distance course on Sunday 11th. On the Sunday race, sailors can win double points meaning any less successful sailors on Saturday still have a chance to win. Following the action, a prize giving ceremony will take place later in the afternoon at Cowes Corinthian with fantastic prizes up for grabs.

VPRS not only provides simpler access to yacht racing but is also centered around socialising with a like-minded community of sailors, with plenty to enjoy during the weekend. Yacht crews and their guests are invited to a welcome reception hosted on Friday evening at The Cowes Corinthian Yacht Club, followed by a class dinner on Saturday.

Entries are now open: apply to enter and book for dinner here.

Please note, participants are responsible for organising their own berthing in Cowes and are advised to book soon to avoid disappointment and secure the best locations.

Keith Lovett, Managing Director & Senior Underwriter at Stoneways Marine commented: "I am delighted that Stoneways Marine will once again be supporting the VPRS National Championship for 2023. As an avid yacht racer myself and knowing so many who compete amongst the VPRS fleet, giving back to the racing communities both local and further afield brings me absolute joy whilst also seeing this event go from strength to strength."

He continued: "What's more, there will be something for everyone during the weekend. Not only does using VPRS mean that entering races is far simpler for seasoned sailors, but it also helps provide racing opportunities for newcomers and those who may just want to race a few times each season."
