Well, the public are legally supposed to enjoy access to the waterfront, at least. Though, that's a never-ending struggle in the U.S., as wealthy people attempt to strangle access for hoi polloi.
I've been reading a bit about some problems in Southern California lately. Here in Michigan, we have similar struggles with Great Lakes shorelines. There's a constant push and pull. At the moment here, the rights for the public to access the shoreline are expanding a bit because of Democratic control of the state, but it's a never-ending process.
Not all yacht owners are wealthy, something I've come to realize lately by following some live-aboard families on YouTube. (It doesn't cost significantly more to own and live on a boat than to own and live in a house.)
But, yachters are a tiny fraction of the population, and the enjoyment of an iconic shoreline really should remain with the public at large.
I wish you much success!
