CAPT SIG — Fishing · MMSI 367598880

CAPT SIG has not broadcast an AIS position for 17 days. The most recent broadcast placed it in the North Atlantic Ocean, on 21 Oct 2026, 18:36 UTC. It was sailing from SHAWCREST to SHAWCREST. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CAPT SIG broadcasts MMSI 367598880, with call sign WDH2561. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

CAPT SIG is classified as a fishing vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full fishing fleet at /vessel-type/fishing and full US flag list at /flag/us.

MarineRadar shows the latest AIS broadcast from CAPT SIG above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

As a fishing, CAPT SIG sits in the same design class as the other fishings listed in the Similar Vessels section of the vessel page, or in the full fishing directory at /vessel-type/fishing.
