A resource for finding deep water slips

[Danielgriffin]

I have that nice problem of a deep water sailboat that draws 8' 2" and was hoping some one knows of a resource to easily find deep water slips when cruising. Looking up the specs on each potential marina is not too efficient and I assume there is some resource where I can just put in my draft and get a list of options when I get tired of being at a mooring or anchor
