Haulover bay will hold maybe 5-6 boats, if memory serves.
That was my back-up spot a dozen years ago, and even it was filled.
Went to my back-up back-up spot, Carvel Bay just to the North, and couldn't get holding. Rocky. Plus the big hill there back-winds you.
My recommendation is to get to your anchorage before noon and totally avoid the stress of late-after "musical chairs."
