N12 boat registration, certification and membership


The Registration Certificate/Measurement Certificate issued for each National Twelve will show the current registered owners name and address, and also shows the current sail plan dimensions and hull/spar weights etc.

National Twelve Class Rules state that change of ownership invalidates the certificate, and any new owner needs to register the boat in their name.

Re-register a second-hand boat, replace a missing or lost certificate, order a sail number for a new boat or renew your membership of the National 12 Owners' Association below.

  • Payments can be made on-line securely by PayPal using a credit/debit card or PayPal account.
