Every yacht that is reporting a position gets its own marker on the fleet Map. Clicking a marker does two things at once: it opens the yacht's detail bubble and it draws that yacht's recent track.
The detail bubble
The bubble is headed by the ship name carried in the AIS broadcast, followed by whichever of these the yacht is currently reporting:
- Last update — the date and time of the most recent position received for this yacht. This is the field to check before trusting a marker's location.
- MMSI — the nine-digit identity the position was matched on.
- Status — the navigational status from the AIS broadcast, in words: Under way using engine, At anchor, Moored and so on.
- Previous destination and Arrival — the destination text the yacht broadcast before and the one it is broadcasting now, the latter with its estimated time of arrival when one is given.
- Speed — speed over ground, in knots.
Fields the yacht is not broadcasting are simply left out of the bubble, so two markers can show different amounts of detail. A reported speed of zero does not replace the previous value, so a yacht that has stopped can still show the last speed it was making — read Status alongside it. Destination and ETA are typed in by the crew on the yacht's own AIS set, not calculated by Nauticare, so treat them as the yacht's own declaration.
The track
Selecting a marker also draws a dashed blue line through the yacht's recent recorded positions, with a dot at each recorded position and arrows along the line showing the direction of travel. The line ends at the marker's current position.
Positions are recorded no more often than about once every ten minutes, so the track is a sampled path rather than every wiggle of the route, and it covers roughly the last couple of hundred recorded positions. A yacht that has only just started reporting has no recorded history yet, so clicking its marker opens the bubble but draws no line.
Only one yacht's track is drawn at a time. Click a different marker to switch the track to that yacht, or click the same marker again to hide the track.
Selecting a yacht on the map does not open the yacht anywhere else in the app — it is a look, not a navigation step. To work with the yacht's records, go to Fleet in the company sidebar and use View on its row.
