MARILYN SHOAL AIS AID TO NAVIGATION MMSI 995036164 IN POSITION 19-48.51S 150-22.80E UNRELIABLE
Reading this warning
- Shoal / reported depth
- Water shallower than the chart shows — a newly found shoal, a reported depth, or less water than charted.
- AIS (Automatic Identification System)
- The radio transponder system that broadcasts a ship's identity, position, course and speed — and can mark a hazard with a virtual beacon.
- Position (degrees and minutes)
- How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
- Inoperative / unreliable / off air
- An aid or radio service is not working as charted or published.
