Deepwater Reef is the far-offshore public box off Ocean City, NJ. If you only have a bay boat, this is the wrong page.

Named drops (sample)

From the Deepwater Reef PDF. We are not inventing GPS for rows the extract did not print cleanly.

  • 224-foot barge Mantank (thebassbarn.com Reef), September 5, 2002 — 38°58.690′ N, 74°11.410′ W
  • NYC Transit Redbird subway cars, July 16, 2003 — sample Redbird Reef I at 38°58.560′ N, 74°10.650′ W
  • 244-foot tanker Vincent Tibbetts (Capt. Walt Hendee) is named on the same PDF. The table wrap did not give us a clean date/coordinate pair, so we are not copying a third-party number. Use the current DEP PDF.

Cape May County MUA tire units (March–May 1994) start the table. We are not pasting every subway-car ID.

Comms

This is not Ocean City Reef. Twenty-three nautical miles is a VHF + inReach trip: fixed-mount DSC radio, current charts, fuel margin, PFDs. Cell coverage is not a plan.

FAQ

Frequently asked questions

Can I run Deepwater in a bay boat?

No. This is 23–23.6 nautical miles off Ocean City in 93–135 ft of water. Plan fuel, weather, crew, and comms as an offshore trip. VHF plus an inReach (or equivalent) — not a phone.

Deepwater vs Ocean City Reef?

Ocean City Reef is the 4.5 nm inshore box. Deepwater is the far-east 1.0 sq mi box near 38°58–59′ N, 74°10–11′ W. Do not mix the two.

Do I still need the saltwater registry?

Yes, if you are 16+ and not solely on a registered for-hire boat. Registry is free. NJ has no saltwater license.
