I, too, have always been impressed with Old Port Cove Marina, Yes, it’s pretty much a powercraft only facility, and a bit pricey, but, hey, these are the Palm Beach’s.
Not also Bill, Jane and Daisy’s recommendation about anchoring in North Lake Worth. That is also an excellent plan for those who don’t need or want marina amenities.

Old Port Cove is very nice, but somewhat pricey. They have brand new state of the art floating docks with pump-outs at each slip. It’s in the middle of all kinds of shopping but you really need a car.
Without a car, you can easily provision for groceries and enjoy several restaurants by anchoring in the north Lake Worth anchorage. The dinghy dock (shown in Skipper Bob’s Anchorage book) is about one block from a Mall with Publix, CVS, etc.
