Arrangements for moorings, launching etc are normally made through class associations, clubs etc. Classes should make these booking early as extra moorings are layed specially for the regattas.
Alternatively, you may make arrangements by sending an email with your requirements to firstname.lastname@example.org
Do you have a mooring at Beaumaris? If you don't intend to use your boat or mooring during the Regattas why not consider making your mooring available for the Regattas fortnight. The Boatman of the RAYC may be able to offer you alternative moorings or a fortnight on the hard at Gallows Point.
If you are able to help please contact the RAYC Boatman:
