CALYPSO — Passenger · MMSI 270427000

CALYPSO has not broadcast an AIS position for 12 days. The most recent broadcast placed it, on 27 Oct 2026, 18:37 UTC. It was sailing from PRAGUE to PRAGUE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CALYPSO broadcasts MMSI 270427000, with call sign OL6135. 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.

CALYPSO is classified as a passenger vessel registered under the CZ flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full passenger fleet at /vessel-type/passenger and full CZ flag list at /flag/cz.

MarineRadar shows the latest AIS broadcast from CALYPSO above, with current position, course, speed, and navigation status.

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 passenger, CALYPSO sits in the same design class as the other passengers listed in the Similar Vessels section of the vessel page, or in the full passenger directory at /vessel-type/passenger.
