Frequently Asked Questions

Where is SAPPHIRE right now?+
SAPPHIRE has not broadcast an AIS position for 17 days. The most recent broadcast placed it in the North Atlantic Ocean, on 22 Aug 2026, 19:19 UTC. It was sailing from CHESAPEAKE HARBOUR to NEW YORK. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.
What are the identifiers for SAPPHIRE?+
SAPPHIRE broadcasts MMSI 367402370. 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.
What type of ship is SAPPHIRE?+
SAPPHIRE is classified as a pleasure craft vessel registered under the US 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 US flag list at /flag/us.

How often is SAPPHIRE's position updated?+
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.
