PRAINHA — Sailing Vessel · MMSI 503167410

PRAINHA has not broadcast an AIS position for 30 days. The most recent broadcast placed it in the Indian Ocean, on 10 Oct 2026, 02:05 UTC. It was sailing from KENDARI to CLASS B. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

PRAINHA broadcasts MMSI 503167410. 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.

PRAINHA is classified as a sailing vessel vessel registered under the AU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full sailing vessel fleet at /vessel-type/yacht and full AU flag list at /flag/au.

MarineRadar shows the latest AIS broadcast from PRAINHA 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 sailing vessel, PRAINHA sits in the same design class as the other sailing vessels listed in the Similar Vessels section of the vessel page, or in the full sailing vessel directory at /vessel-type/yacht.
