A "villa with mooring rights" sounds like a single transaction. It isn't. In Spain, marina berths in Puerto Banús and Sotogrande are governed by a 1928-rooted public-domain regime (Ley de Costas, Ley 22/1988, modified by Ley 2/2013). What changes hands when you buy is a concession or a transfer of usage rights — not freehold. Buyers regularly believe they own a berth they merely lease for the remaining concession term. The difference matters when the concession expires.
Marina berths in Puerto Banús and Sotogrande are administrative concessions over public maritime domain, not freehold property. What an owner sells is the transferable usage right for the remaining term of the marina's concession; the Puerto Banús concession has been extended to 3 October 2066. A "purchased" berth is effectively a long-lease asset whose value depends on the years remaining. Transfer and association fees are set by each marina — ask for them in writing; no public source gives a band. A villa sale does NOT automatically include the berth unless explicitly stated in the escritura; the berth is a separate transferable asset.
Under the Spanish Coastal Law (Ley 22/1988), the maritime-terrestrial public domain is state-owned and inalienable, and marinas operate under administrative concessions. Puerto Banús (Puerto José Banús) is run by its concession holder, Puerto José Banús, S.A., under an administrative concession of the Junta de Andalucía (Agencia Pública de Puertos de Andalucía), extended to 3 October 2066. The concession holder then grants derived usage rights to berth holders.

The berth holder pays the marina an annual usage fee (cuota de uso) and, on transfer, both buyer and seller pay administrative transfer fees to the marina. Berth purchase price is set freely between buyer and seller in the open market, NOT regulated.
What a berth costs is not published. The berth concession is priced separately and negotiated privately; the desk shares current bracketing on introduction rather than publishing a band nobody can source.
Note the residual concession term. A usage right is worth what the years left on the concession make it worth, so ask the marina in writing for the term that applies to the berth being offered and for the conditions attached to it.
