Running out of Shark River Inlet
Blue marlin fishing out of Belmar starts at Shark River Inlet. Fin-ominal says its boats sail out of the inlet, and this page works from that departure point. From there, Belmar boats reach a short list of named reefs, wrecks and a deep trough called the Mud Hole. The sections below give the depth and position of each piece of structure.
Nearby reference points
Two shore references anchor the distances below:
- The Sea Girt Reef is measured from Sea Girt.
- The Shark River Reef is measured from Manasquan.
Neither distance runs from Belmar, so adjust for that when you build a route.

The Atlantic Northeast blue marlin guide (see also the Atlantic Northeast offshore fishing guide) explains how fish move through the region and how far boats run in the Northeast. For gear and method, see billfish tackle and technique. This page covers only the structure off Belmar.
