DBSC Racing Marks Chart 2025 applicable for 2026. Note that Merrion mark has been moved slightly to facilitate marine survey work. The position of Battery mark has been updated. Omega mark will not be a data buoy this year. The Racing Marks Chart has not been updated to show these small changes – it shows the approximate positions of the marks.
You can download all the course card documents and the Keelboat Race Times in one zip file.
The course cards and mark locations are also available in machine-readable form – these are not official documents, and are used at your own risk.
