The information in our boat register listings is on a best endeavours basis. We suspect that some of it may be inaccurate. It has been assembled from a number of sources. My thanks go in particular to Veronica Falat, and Graham Lamond who have collated and supplied much of the information on British boats here, to Ron Humphrey and Ray Sebo who have supplied details on boats in Australia, and Edgar Kelly and Brian McKee for details from Ireland.

If you have any information to add to the register, then please let me know. We are particularly interested in building up the details of the non-British Isles boats.

The national letters with the sail number are those for what is thought to be the country in which the boat was first sailed. If the boat is known to have moved to another county, that is shown in the comments column. In some cases this country is not known, or the country does not have a set of national letters (in which case the country appears in the comments column). When the country has changed its name, the countries current name is used.

The year given for championship successes for those countries that sail in the southern hemisphere season refers to the year in which that season started, e.g. 1996 would be for the 1996-7 season.

The Flying Fifteen class register serves as a living record of these classic sports boats scattered across the globe, from the original British fleets to strong contingents in Australia, Ireland, France, and beyond. Compiled from multiple sources and maintained on a best-efforts basis, the register helps owners trace a boat's history, verify its specifications, and connect with the broader community. Whether you own a competitive modern hull or a cherished classic from decades past, adding your boat's details helps preserve the class heritage. The register is particularly valuable for tracking the movement of boats between regions and ensuring that the lineage of these elegant two-person keelboats remains documented for future generations of sailors.
