Question 1

Where is HYDRA right now?

Accepted Answer

HYDRA has not broadcast an AIS position for 6 days. The most recent broadcast placed it in the Mediterranean Sea, on 3 Sep 2026, 04:50 UTC. It was sailing from GIBRALTAR to GIBRALTAR. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for HYDRA?

Accepted Answer

HYDRA broadcasts MMSI 235116854, with call sign 2JLE2  . 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.

Question 3

What type of ship is HYDRA?

Accepted Answer

HYDRA is classified as a dredger vessel registered under the GB flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dredger fleet at /vessel-type/military-special and full GB flag list at /flag/gb.

Question 4

How can I see the live position of HYDRA?

Accepted Answer

MarineRadar shows the latest AIS broadcast from HYDRA 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.

Question 5

How often is HYDRA's position updated?

Accepted Answer

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.

Question 6

What class is HYDRA?

Accepted Answer

As a dredger, HYDRA sits in the same design class as the other dredgers listed in the Similar Vessels section of the vessel page, or in the full dredger directory at /vessel-type/military-special.
