EMERALD HARMONY — Passenger · MMSI 515214716

EMERALD HARMONY has not broadcast an AIS position for 6 days. The most recent broadcast placed it in the South China Sea, on 31 Oct 2026, 23:30 UTC. It was sailing from HO CHI MINH to MY THO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

EMERALD HARMONY is classified as a passenger vessel registered under the KH flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full passenger fleet at /vessel-type/passenger and full KH flag list at /flag/kh.
