In Palm Beach County the house is the easy part. Whether a 60, 80 or 100-foot boat can live behind it depends on the inlet, the bridges and the water at the dock, and the listing sheet only tells you part of that.
Palm Beach County has one deep-draft inlet. The Lake Worth Inlet, which locals call the Palm Beach Inlet, was dredged to 35 feet in 1967 and has been maintained at that depth since, because it is the entrance channel for the Port of Palm Beach. It sits between the Town of Palm Beach and Palm Beach Shores at the southern tip of Singer Island, and it is a straight run from the sea buoy into the Intracoastal.
The Jupiter Inlet, 11 miles to the north, is a different animal. Average depths run 6 to 12 feet, dredged channels reach 20 feet, and shifting sandbars and strong tidal currents call for local knowledge. It serves Jupiter, Tequesta and the Loxahatchee River communities well for sportfish boats and cruisers, but owners of larger yachts in the north county tend to run south to the Palm Beach Inlet or keep the boat at a marina near it.
Between the Palm Beach Inlet and the waterfront neighborhoods north of it, three bridges cross the Intracoastal. Only the first is fixed.
| Bridge | Type | Closed clearance | Opens | Who it affects |
|---|---|---|---|---|
| Blue Heron (SR A1A), ICW mile 1017.2 | Fixed, high level | 65 ft | Never needs to | Every home on Singer Island’s lagoon side and in Riviera Beach north of the bridge |
| Parker (US 1), mile 1013.7 | Bascule | 25 ft | Quarter and three-quarter hour | North Palm Beach, Old Port Cove and the Lake Worth Lagoon north of US 1 |
| PGA Boulevard, mile 1012.6 | Bascule | 24 ft | Hour and half hour | Frenchman’s Creek, Juno Beach and everything north to Jupiter |
So the rule of thumb runs like this. Palm Beach Shores and the Palm Beach side of the inlet have no bridge at all between dock and ocean. Singer Island’s canal neighborhoods, Palm Beach Isles, Yacht Harbor Manor and Estates, Pine Point and the Lake Drive enclaves, pass under one high-level fixed span, the Blue Heron Bridge, with 65 feet of charted clearance and no drawbridges. That clearance is why boats of 100 feet live behind houses on the island, and why many MLS listings there still check “No Fixed Bridges”: read that box as the listing agent’s description of the route, and confirm the route and clearance for the specific house and boat. North of the Parker Bridge, a boat taller than 25 feet waits for an opening twice an hour; north of PGA Boulevard, twice more. Charted clearance is measured at a set water level, so the real clearance changes with the tide: a sportfish with a tower or a yacht with a tall mast should check its air draft against the current NOAA chart and the tide before relying on 65 feet.
BeachesMLS listings carry a set of waterfront fields that tell you a great deal if you know what each one is saying. On a deep-water listing, those fields might read: No Fixed Bridge, Ocean Access, Canal Front, Intracoastal, Point Lot, Seawall, Canal Width 121 Feet or More, Electric Available, Lift, No Wake Zone, Private Dock, and Over 101 Ft Boat.
On Singer Island the houses with dockage for the largest boats are on the Intracoastal side: Palm Beach Isles, Yacht Harbor Manor, Yacht Harbor Estates, Pine Point Road and the Lake Drive enclaves. In the twelve months to October 2026 the island’s canal neighborhoods recorded 38 single-family sales at a median of $1,560,000, and the sales above $5 million were all deep-water lots. The Singer Island guide covers each neighborhood, and the October 2026 market report has the numbers by street and building.
Palm Beach Shores, at the inlet, has the shortest run to the ocean in the county. North Palm Beach, Lost Tree and Juno Beach have fine docks and drawbridges to plan around. Admirals Cove and the Jupiter waterfront have the Jupiter Inlet, which is a sportfish inlet, or a long run south on the Intracoastal to the Palm Beach Inlet.
