Offshore sail numbers

The RYA Technical Department issues offshore sail numbers, essential for all racing yachts and advisory for cruising yachts venturing to sea

These sail numbers are an important way of uniquely identifying a yacht for search and rescue purposes and are a requirement of the Racing Rules of Sailing, Rule 77 - Identification on Sails. The RYA recommend that all yachts have a unique sail number.

The RYA is responsible for issuing L,N,M (multihull) & X series with L being the current in sequence series. We are also responsible for updating historic Y & T series.

Allocation of a single number is free of charge to RYA Gold Members, £20.00 RYA Personal Members, and £40.00 to non members and companies.

It is also possible to obtain an Out Of Sequence sail number. These are a great way of personalising your vessel with a meaningful number. These are subject to availability, for further details and prices please contact either technical@rya.org.uk or call 02380 60 4200.
