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 tug, MASTER sits in the same design class as the other tugs listed in the Similar Vessels section of the vessel page, or in the full tug directory at /vessel-type/tug-pilot-vessel. MASTER has a gross tonnage of 280 GT.
