I drew five feet on my two previous boats.
I have anchored there often with no issue.
Even to close to the cemetery.
But there during a spring/neep tide you might touch the soft mud bottom.
In a pinch I think you could get 4-5 boats there
Holding is pretty good.
There is a designated dingy dock.
I was a seaport member and never reported to the dockmaster.
At that time the stationary heads and showers were open to public.
You might wish to consider membership there
It is fun to dingy into town.
