Sorry to bring a touch of reality to the table but FYI:
All of the operating profits from the Crown Estate Scotland coastal 'portfolio' are given to the local authorities via an agreement reached with COSLA (Convention of Scottish Local Authorities) - the authorities whose coastline generates the greatest revenue receive the largeer shares which, in some cases, can be between £1million and £2million a year - to be spent on projects targeting coastal communities.
South of the border (ie England and Wales) then the income is passed directly to the piublic purse by The Crown Estate (TCE), though TCE also have a number of initiatives by which coastal communities can apply for funding directly.
The Crown Estate is effectively a land management company, managing land and assets owned by 'The Sovereign' (not the Royal Family) on behalf of the public. It dates back to 1760 when George III (who was financially inept) passed the Crown's assets to Parliament in return for an annual stipend - this became the Civil List. Over the past 10 years TCE have generated an income of over £4 billion for the public purse (aka the 'consolidated fund') which is passed to the Treasury.
