Current, Lots of current. Dock there and you will be able to dock almost any where. I was there for about 5 years. Had a 27 Chap, never had the bimini up due to fact we would have to take it down for high tide. You can get in and out most times if you are careful. Full moon high tides are a no-no...
out of all the times I went in and out only managed to get stuck out once. I picked up a few extra passengers, put them on the bow and in we went. There is a spot on the left side that is cut out about an inch or two. We used that many times and would use people to stand on the bow and walk us thru.
There is also a sunken barge that you want to find out where it is. Saw many boats go over it at high tide, many props destroyed there...
