PIONEER — Sailing Vessel · MMSI 235030886

PIONEER has not broadcast an AIS position for 9 days. The most recent broadcast placed it in the North Sea, on 29 Oct 2026, 14:25 UTC. It was sailing from HARWICH to BRIGHTLINGSEA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

PIONEER broadcasts MMSI 235030886. 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.

PIONEER is classified as a sailing vessel vessel registered under the GB 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 GB flag list at /flag/gb.

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, PIONEER 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.
