Axel Carlson Reef — public NJ artificial reef off Mantoloking

Axel Carlson is a public NJDEP Fish & Wildlife artificial reef about 2 nautical miles off Mantoloking. It is not a secret wreck. Site corners, depths, and deployments come from state PDFs that are marked not for navigation.

2005 location note
DEP news: four miles southeast of Manasquan Inlet and two miles offshore of Mantoloking

Axel Carlson is one of the public hard-bottom sites Ocean County boats actually run — a state reef, not a whispered wreck. NJDEP Fish & Wildlife has been building a coastal reef network since 1984. This site sits in the Mantoloking / Manasquan neighborhood of that network.

Where the state says it is

The DGPS location sheet titles the site “AXEL CARLSON REEF SITE — 2.0 Nautical Miles off Mantoloking NJ.” The August 2021 three-map PDF lists 2.1 nm offshore, 5.2 square miles, and a 66–82 ft depth band, with the map itself marked not for navigational purposes.

A May 31, 2005 DEP news release described the same site as four miles southeast of Manasquan Inlet and two miles offshore of Mantoloking, and published construction-era corner coordinates while granite from New York Harbor was being dumped to build rock ridges. Those 2005 corners are close to the current reeflocs sheet, not a second secret box.

If the two state documents disagree by a tenth of a mile, believe the PDF you downloaded today — not a blog reprint and not this page cached in an answer engine.

What “wreck fishing” means here

The state table is a catalog of deployed material, not a treasure map of intact historic ships. Entries we can name without inventing anything include:

  • M-60 Patton tanks and M-113 APCs from 1994–1998, including memorial names on the state sheet
  • 92-foot tug Colleen, deployed August 3, 1996
  • 165-foot tanker barge Capt. Ed Schmidiger
  • Tire units and later USACE dredge-rock cells (2008–2009)
  • 68-foot trawler Mc Ginty (Ward’s Wreck Reef, May 7, 2010)
  • 53-foot crew boat NY Harbor Charlie (August 9, 2016)

We are not copying the hundreds of remaining rows. If you need a specific ID, open the Axel Carlson PDF. Materials move, sand over, and get new neighbors.

Fish, rules, and Full Access Zones

DEP’s reef program copy says these structures provide habitat for black sea bass, tautog, and lobster. That is program language, not a Cast Cruise catch report from this GPS.

New Jersey does not issue a saltwater fishing license. Recreational anglers 16+ still need the free NJ Saltwater Recreational Registry. Size, season, and bag limits live on the 2026 Marine Digest — we will not paste them here so they cannot rot on this URL.

The Axel Carlson map shows a Full Access Zone (FAZ). Commercial reef-gear rules changed in 2015; read NJDEP’s FAZ fact sheet instead of guessing whether you can drop a pot.

What to put on the boat

A 7–9 inch plotter with current coastal charts, a fixed-mount VHF with DSC and GPS, and PFDs people will actually wear. Handheld VHF is a backup. This is a short Ocean County run, not a reason to skip Channel 16.

See Barnegat Light Reef for the public reef people mean when they search “Barnegat Light wreck,” 2026 seasons before you keep a fish, and NJ saltwater rules for the registry.

FAQ

Frequently asked questions

Is Axel Carlson a secret wreck?

No. It is a named site in New Jersey’s public artificial reef network. NJDEP Fish & Wildlife publishes maps, a deployment table, and DGPS corners.

Can I punch these corners into the plotter and go?

Use them only as a starting box from the state sheet. The Axel Carlson PDF is marked not for navigational purposes. Confirm on the live DEP file and a current NOAA chart.

Do I need a New Jersey saltwater fishing license?

New Jersey does not sell a saltwater license. Anglers 16 and older must register free with the NJ Saltwater Recreational Registry unless they are solely fishing on a registered for-hire boat. Size, season, and bag limits still apply — check the current Marine Digest, not this page.

What is actually on the bottom?

The August 2021 map legend lists concrete, dredge rock, military vehicles, reef balls, ships, and tires, plus a Full Access Zone. Named pieces in the state table include M-60 tanks, M-113 APCs, the 92-foot tug Colleen (1996), and later rock cells from the U.S. Army Corps of Engineers. We have not dived it.
