The water
John Levique and Joseph Silva were sailing home from selling green turtles in New Orleans when the Great Gale of 1848 caught them. Looking for a familiar way back into Boca Ciega Bay, they found an opening that had not existed the week before.
Both men later claimed 160-acre federal land grants on condition that they settle the ground around the new pass.
Bay-side water here is warm, protected and slow to flush. The pass a short run away does the tidal work, but very little of it reaches a hull tucked back in the bay.
At 0.3 miles from John's Pass, this water never stops moving. Cleaning gets planned around slack tide, not around the calendar.
Madeira Beach Moorings, Madeira BeachMadeira Beach Moorings lies about 0.3 miles from John's Pass, with Blind Pass roughly 4.6 miles off. It sits effectively on the inlet itself, and that distance is the single best predictor of how fast a hull fouls here.
Water here turns over on every tide. That constant exchange keeps slime down and temperatures closer to Gulf conditions, but it delivers an unbroken supply of barnacle larvae to anything that holds still. Hard growth dominates, and it sets fast.
A private marina with a settled fleet gives us the most useful thing possible: the same hulls over time, so the cadence gets sharper with every visit.
Timeline
The army opens a rest post on Clear Water Harbor. The peninsula is barely settled.
A lighthouse goes up at the mouth of Tampa Bay. The Great Gale destroys it the same year.
A Category 4 hurricane lands at the mouth of Tampa Bay and cuts a new inlet through the barrier island.
Levique and Silva, sailing home from selling green turtles in New Orleans, find the opening and sail through.
Both men claim 160-acre federal grants on condition they settle the ground around the pass.
A two-lane drawbridge finally spans the pass.
The crossing is replaced twice more as traffic and vessel size grow.
Wilson Hubbard persuades Madeira Beach to build it. It now runs 1,100 feet.
Things worth knowing
Distance to the nearest inlet is the strongest single predictor of fouling rate. At 0.3 miles from John's Pass, with Blind Pass a further 4.6 miles off, this berth sits right in the tidal stream.
Madeira Beach, weekday office hours. Madeira Beach, on Boca Ciega Bay, 0.3 miles inside John's Pass — well within our regular run.
Growth in Pinellas is not linear, and at 0.3 miles in the seasonal swing is muted by constant exchange. A cadence set for August will be wrong in January.
Bare metal fouls faster than painted surface everywhere on this coast, and in moving water it is relentless. Props, shafts and struts usually signal the timing before the paint does.
Manatees, dolphins and grass beds share Boca Ciega Bay. Method matters as much as schedule — media matched to the paint, and nothing scoured into the bottom.
With 7 reviews it is one of the quieter entries on our list — smaller fleets tend to mean more stable, more predictable fouling.
From the diver
Boca Ciega runs shallow and warm, and warm shallow water grows things. Expect a real barnacle set from May through October and a heavier slime layer than you would see in open Gulf water.
Flushing is the variable that matters most. A slip near the mouth of a canal turns over far more water than one at the dead end, and two boats a hundred yards apart can foul at noticeably different rates.
Because growth here is fast rather than gradual, cadence beats intensity. Frequent light cleans hold the paint far better than waiting for a heavy set and then scrubbing hard to catch up.

We dive Boca Ciega Bay and know how it behaves through the season. Tell us the boat and the slip and we'll send a number and a cadence that fits the water it actually sits in.
