I reviewed these notes in August 2021. Firstly, this marina is now run by the Marina Group along with about half a dozen Welsh Marinas. Their main website covers all these Marinas and unless you download their brochure (which again covers all the Marinas) you will get frustratingly lost. Our link in the Berthing and Mooring section takes you straight to the pages you need in their multi facetted IT. The posh hotel on the hill above the marina is ambiguous as to their attitude to non-residents and enquiries have been made.
