Question 1

Where is MASTERPLAN right now?

Accepted Answer

MASTERPLAN has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the English Channel, on 5 Sep 2026, 15:02 UTC. It was sailing from FALMOUTH to FALMOUTH. 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 MASTERPLAN?

Accepted Answer

MASTERPLAN broadcasts MMSI 235107153, with call sign DATAHUB. 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 MASTERPLAN?

Accepted Answer

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

Question 4

How can I see the live position of MASTERPLAN?

Accepted Answer

MarineRadar shows the latest AIS broadcast from MASTERPLAN 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 MASTERPLAN'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 MASTERPLAN?

Accepted Answer

As a pleasure craft, MASTERPLAN sits in the same design class as the other pleasure crafts listed in the Similar Vessels section of the vessel page, or in the full pleasure craft directory at /vessel-type/yacht.
