Each yacht running the on-board app has exactly one registered device: the server aboard. It is shown in the Device section of Vessel Settings → On-board app.
The device card
The card is named after the yacht (for example Aurora on-board app) and shows:
- Active, or Revoked with the date it was revoked.
- Device ID: the identifier to quote when raising a support issue.
- Last seen: the last time the on-board server contacted the cloud. It updates on every sync, so on a connected yacht it is never more than a minute or two old. On a yacht at sea it shows when the connection was last up.
- Registered: when the device was created during the install.
- Protocol: the sync protocol version the device uses.
If nothing is registered, the section reads No active vessel device. Register one from the install flow.
Rotating the token
The on-board server signs in to the cloud with a secret token. Rotate token on the device card issues a new one.
The Rotate vessel device token window lets you choose between two modes before confirming:
- Routine rotation: the current token keeps working for 24 hours, so sync continues while the on-board server is updated.
- Token may be compromised: the current token stops working immediately. Sync pauses until the new token is installed; changes made on board stay queued and are not lost.
In either case, the new token must be written to the on-board server's .env and its service
restarted before the server can use it. Do not rotate unless someone can reach the server to do
that.
Once you confirm with Rotate token, the new token is displayed with a Copy to clipboard button. It is shown only once. Nauticare stores only a fingerprint of it, never the token itself. If it is lost, the only way back is registering a new device.
Rotating does not touch any data. Work done aboard keeps queuing while the server cannot authenticate, and uploads as soon as it can again.
Revoked devices
Devices are never deleted, so the history stays auditable. Past devices are collapsed behind Show N revoked devices below the active card, each with the date it was revoked. A device is revoked automatically when an install is cancelled or a decommission completes.
