Holy crap!!!! Just noticed I had a complete brain fart!!! I was answering about Brewers even though I wrote Lindbergh. Reboot now....

I've seen boats anchored for weeks in Lindbergh, only moving when a swell would come in making it too rolly for comfort.

At one time it was discussed that dredge material from the Havensite dock area would be dumped there. That project never happened. Some material was dredged from Lindbergh and was used as fill for the airport expansion decades ago. Holding is excellent in deep sand.

Back to paying attention before typing!!!
