TOP WEATHER — Cargo · IMO 9631462

TOP WEATHER has not broadcast an AIS position for 180 days. The most recent broadcast placed it in the Sea of Japan, on 10 May 2026, 21:49 UTC. It was sailing from FUKUYAMA to NEWCASTLE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

TOP WEATHER broadcasts MMSI 373180000 and is registered as IMO 9631462, with call sign 3FMM8. 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.

TOP WEATHER is classified as a cargo vessel registered under the PA flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full cargo fleet at /vessel-type/cargo and full PA flag list at /flag/pa.

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.

TOP WEATHER is classed by LLOYD'S SHIPPING REGISTER, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a cargo, TOP WEATHER sits in the same design class as the other cargos listed in the Similar Vessels section of the vessel page, or in the full cargo directory at /vessel-type/cargo. TOP WEATHER has a gross tonnage of 33,125 GT.
