What you can do

    Search certificates

  • My Boats

    Keep your boats' data online. Add a boat from its certificate, then change its sails, rig, crew weight or anything else its data file holds, in the online editor or offline in the IMS Editor.

  • Test certificates

    See what a change would do before you make it. The current ORC VPP rates your boat's data and sends you a test certificate with the new ratings.

    Start from My Boats

  • Speed guides

    Polar diagrams and tables of boat speed, angles and heel for every wind speed and sail, with Expedition and SYLK files for your instruments and routing software. Made from a valid certificate or from your own test certificate.

How a test certificate works

  1. Register

    An account is free. All you need is an e-mail address, or your Google account.

  2. Add your boat

    Find its certificate and add it to My Boats. Its data file comes with it.

  3. Change what you want to try

    A new headsail, a lighter crew, a longer pole: edit the data online, or offline in the IMS Editor.

  4. Run the VPP

    Request a test certificate. The result is e-mailed to you, and then its speed guide and target speeds can be ordered too.

Credits: you pay for what is delivered

Test certificates and products are paid for in credits, bought online by card in packs; larger packs cost less per credit.

When you request a test certificate or order a product, its price is held from your credits and charged only once it has been delivered. A run that fails costs nothing.

Prices in credits

Certificate copies, scratch sheets and the software: free.

Software and data

  • IMS Editor

    Edit a boat's data file on your own computer, check it and print it, then upload it to My Boats.

  • ORC API

Good to know

What only a rating office can do

Sailor Services rates the data you give it. It can't change a hull's offset file or measure its stability, and a test certificate is for trying changes: the certificate you race with comes from your rating office.

Always the current VPP

Test certificates are made with the latest release of the ORC VPP, whose version is printed on each. Early in the year one release may follow another, and ratings can change with it.
