Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

THIRTY NINE is classified as a sailing vessel vessel registered under the MT 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 MT flag list at /flag/mt.

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.
