King mackerel fishing out of Stuart: when and where boats run

King mackerel fishing out of Stuart centers on the reef areas off St. Lucie Inlet. Boats run to Sandpile, Six Mile and Loran Tower, mostly in 50 to 90 ft. Fish show in better numbers on reefs in that band, and a typical depth is about 50 ft.
Local operator calendars list king mackerel. For timing across the Treasure Coast, read the regional picture (see also the Atlantic Southeast fishing guide) and match it to what you see on the water.
Start in the 50 to 90 ft band, where the 80 ft reefs are the core. From the inlet, the run falls into three tiers: nearshore Sandpile, the 80 ft reef line, and deeper named structure at 180 and 200 ft.
| Tier | Where | Depth |
|---|---|---|
| Nearshore | Sandpile reef | Nearshore reef |
| Core band | Six Mile, Eight Mile, Loran Tower | 80 ft |
| Deep structure | Boo McCulley, Brause Girls | 180 ft and 200 ft |
Reading conditions at St. Lucie Inlet
NOAA tide station 8722207 is the St. Lucie tide source. Check the tide there before you run the inlet, and look up wind, wave height and period in the official marine forecast.

Sandpile reef
Sandpile is the nearshore reef and one of the three areas boats run to.
Six Mile and Eight Mile reefs
Both reefs sit at 80 ft, inside the 50 to 90 ft band. Six Mile is named for six miles and Eight Mile for eight miles. Six Mile is one of the three areas boats run to.
Loran Tower (Hobe Sound)
Loran Tower sits at 80 ft, off the Loran tower in Hobe Sound. It is inside the band and is one of the three run areas.
Pushbutton Hill
Pushbutton Hill, known as the Hill, is named structure offshore of St. Lucie Inlet.
The Rankin
The USS Rankin wreck is named structure near Stuart.
Boo McCulley and Brause Girls
Boo McCulley (Borocho) sits at 180 ft, 9 miles offshore of St. Lucie Inlet. Brause Girls (Penobscot tug) sits at 200 ft, 9 to 10 miles offshore, reached from Stuart. Both are outside the 50 to 90 ft band where fish show in better numbers, so treat them as named structure.
How kings are fished out of Stuart

Local anglers troll and fish live baits around the reefs. For rigging and baits in more depth, use the species guide.
Trolling the reefs
Trolling is a local method on the reefs. It lets you cover reef areas and find fish.
Live baits around structure
Live baits are fished around the reefs. Work them close to the structure you marked.
Working the 50 to 90 ft band
Fish show in better numbers on the reefs in the 50 to 90 ft band, and the typical depth is about 50 ft. The 80 ft reefs (Six Mile, Eight Mile, Loran Tower) sit inside the band, so look there first. Depth alone doesn’t guarantee fish.
