This page exists for the boat rather than the building. Key Biscayne sits out in Biscayne Bay, so island docks tend to face open water, and the run south around Cape Florida to the Atlantic keeps clear of the Rickenbacker Causeway. The canal lots of the Cape Florida sections are the usual draw for sailboat and sport-fishing owners. The listings also include condominiums such as Grand Bay Tower, where the waterfront flag describes the building, so ask in writing whether any dockage conveys before you count it. On the island the practical limit is usually depth rather than clearance: the bay shallows and the flats toward Stiltsville decide the draft you can run, so check a chart and sound the water at the dock at low tide before buying a Key Biscayne home for a keel boat.
