TUBBATAHA — SAR · IMO 9809411

TUBBATAHA has not broadcast an AIS position for 26 days. The most recent broadcast placed it in the North Pacific Ocean, on 12 Oct 2026, 18:27 UTC. It was sailing from BITUNG to ZAMBOANGA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

TUBBATAHA broadcasts MMSI 548126500 and is registered as IMO 9809411, with call sign 4DFL-9. 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.

TUBBATAHA is classified as a sar vessel registered under the PH flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full sar fleet at /vessel-type/tug-pilot-vessel and full PH flag list at /flag/ph.

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 sar, TUBBATAHA sits in the same design class as the other sars listed in the Similar Vessels section of the vessel page, or in the full sar directory at /vessel-type/tug-pilot-vessel. TUBBATAHA has a gross tonnage of 321 GT.
