Every offshore run from Port Mansfield starts at the Mansfield jetties, and blue marlin fishing here happens well past the nearshore rocks and the public reef. If you’re running your own boat, this guide covers the named structure on the way out with depths and distances, the local trolling method, and the charters that list blue marlin. Plot the landmarks from the Port Mansfield port guide before you clear the channel entrance.

Where boats run from the Mansfield jetties
Every run starts at the jetties, and every distance below is measured from them. The nearshore structure serves as a set of landmarks on the way out and is not marlin ground.
| Structure | Depth (ft) | Distance/Location | Note |
|---|---|---|---|
| Mansfield jetties (channel entrance) | unlisted | Start of every run | Fixed reference point |
| North Rocks | unlisted | Extends about 12 miles from the beach | Nearshore rock |
| Snapper rock piles | 48 | Group 9 to 12 miles east of the jetties | Rocks east and north of the jetties, no individual names |
| Port Mansfield public reef | 70 | unlisted | TPWD Public Reefing Program, 160 acres under an Army Corps permit |
| Offshore trolling water | unlisted | Offshore, no ground named | Where local listings troll for blue marlin |
The rocks at 48 ft and the reef at 70 ft are bottom-fishing country, and the marlin run continues past them.
