Seawall with a large void where the concrete has eroded away, filled with repair cement

Jupiter sits at the mouth of the Loxahatchee River, where the river, the Intracoastal and the ocean meet at the Jupiter Inlet. It is the north end of our service area and one of the busiest, with inlet charter boats at Burt Reynolds Park and yachts on 500-plus private docks in Admirals Cove, all in water that goes from nearly fresh upriver to fully salt at the inlet.

The Loxahatchee, the inlet and the salt gradient

The Loxahatchee has been a National Wild and Scenic River since 1985, and it runs from freshwater creeks into a brackish estuary that gets saltier as incoming tides mix in from the inlet: above 30 parts per thousand just seaward of the inlet, 11 to 25 across most of the estuary, and below 0.1 in the upper Northwest Fork. Where your dock sits on that gradient decides what grows on your hull and how fast your zincs wear, which is why the diver records both every month rather than guessing.

The inlet is natural, with tides of about 2 to 3 feet, jetties built in 1922 and dredging that has kept it open since it was closed during the war years of 1942 to 1947. The waters around it, from the SR 707 bridge to the Indiantown Road bridge, are a year-round idle-speed zone outside the channel; the Loxahatchee has a 300-foot shoreline slow zone plus seasonal slow speed, and the backwaters of Lake Worth Creek, including Admirals Cove, are slow. Slow water is where growth stays put.

Where we work in Jupiter

Admirals Cove, west of the Intracoastal, is a gated club community of about 975 acres with roughly 6 miles of waterways and more than 500 private docks, and it is our largest single stop in Jupiter. Jupiter Harbour, a gated marina community on North US-1 where the inlet meets the Intracoastal, is the other. Burt Reynolds Park on North US-1 has 2,000 feet of Intracoastal frontage, six ramps (the west-side ramps open around the clock) and county day-use slips; DuBois Park at the inlet's south jetty and Waterway Park have county slips and a ramp too. Jupiter Inlet Colony is a separate town on Jupiter Island, and the Jupiter Inlet Lighthouse of 1860 stands on the north bank. ZIP codes 33458, 33469 and 33477 cover the waterfront.

Docks and seawalls on a brackish river

Admirals Cove and Loxahatchee docks sit in slow, brackish water where oysters and shipworms both thrive, and we clean their pilings without pickaxes or chisels before inspecting them bare. We have not researched a Jupiter seawall ordinance, so a seawall inspection here is about the wall's condition and the lender-required documentation a sale needs: $250 for a home, $350 for a multi-family or commercial property, cleaned first, with cracks filled all the way through with custom cement tubes.

Jupiter questions

My boat is on the Loxahatchee River. Does brackish water change the cleaning schedule?

It changes the growth, not the schedule: every 30 days, with every two weeks if the photos show a nutrient-rich spot. The river gets fresher upstream and saltier toward the inlet, so an upriver boat grows more slime and a boat near the inlet grows more barnacle, and the diver's monthly photos tell you which you have.

Do you clean boats in Admirals Cove?

Yes, at private docks throughout the community and along Lake Worth Creek, every 30 days, and the owner doesn't need to be there. The divers call ahead and text you right before each visit, and the report and photos follow.

I run the Jupiter Inlet a lot. What do you check besides the hull?

The running gear, the waterline and the zincs, in that order. Running the inlet scrubs the painted hull but not the props, shafts and rudders, where bottom paint can't stick and barnacles settle while the boat sits; the diver cleans those, brushes the waterline and records each zinc's percentage, replacing at 50%.

Can you inspect my seawall near the inlet?

Yes. Residential inspection is $250 and multi-family or commercial is $350, both with the lender-required documentation that almost every waterfront sale needs, and the growth comes off first so the diver can see the wall.

Booking in Jupiter

Use the form or call 561-666-3716 with the boat's length, where it lives (Admirals Cove, Jupiter Harbour, a Loxahatchee dock or the Intracoastal) and whether the hull is painted. Tell us roughly how far upriver the dock is, since that sets what the diver expects to find. Jupiter is the top of our route, so we group visits; nobody needs to be home.
