Welcome to alerting in Wayfinder! Follow the steps below to configure your very own Wayfinder alerts. Tune in to the data that matters most in real-time and follow along with your fleet.

1. Set and review vessel specific alerting thresholds
2. Opt-in to specific alert types
3. Select vessels

For more information on setting operational safety limits, please review Set and Confirm Safety Limits

1. Set and review vessel specific alerting thresholds

The thresholds that you see here are typically set by your fleet's safety teams during vessel onboarding and should not be changed by individual operators on a frequent basis.

If needed, you can reference the current limit in the "Profile" tab of the vessel details page. Note that these are distinct from operational routing limits, as they only inform alert behavior, not routing decisions. Raise the threshold if you want more margin before being notified; lower it if you want an earlier heads-up.

2. Opt-in to specific alerts types

Wayfinder offers a choice of five different alerts and each user can customize the alerts that they care about. Any time that an alert threshold is hit for a given vessel, the alert is sent to any users that have subscribed to the alert and the vessel.

Please note: Each alert type includes de-duplication logic to prevent users from receiving more than one notification for the same event. For weather-based alerts in particular, a new notification is only sent if the timing of the situation has changed enough to represent a meaningfully different state.

1. Route Rejection Alerts: A route rejection alerts will be sent when a Wayfinder user clicks reject on a suggested route. Only one alert is sent for a given route suggestion.

1. Off-Track Alerts

   • Trigger: New AIS position received for a vessel (ingested every 30 minutes)
   • Condition: Distance between the AIS lat/lon and the expected lat/lon along the Wayfinder route exceeds the set threshold (default 50 NM)
   • De-duplication: Only sent for the first time an AIS position is outside of the threshold for a given route; when a Sofar Router provides new daily guidance or anyone imports a route in Wayfinder, this is considered a new route and could trigger a new off-track alert

2. Tropical Storm Proximity Alerts

   • Trigger: Tropical storm data is updated (every 1 hour)
   • Condition: The vessel is expected to be within the set threshold (default 500 nm) distance of a tropical storm within the next 72 hrs based on most recent AIS or predicted position along their route.
   • De-duplication: A new notification is sent only when the forecasted position & time is still within the proximity threshold and ≥6hrs from the forecasted position & time of the previously sent notification.

3. High Wind Alerts

   • Trigger: Weather forecast is updated (every 6 hours)

   • Condition: The vessel is expected to encounter wind speed values that exceed the set threshold for a 6+ hr period in the next 72 hours (based on Wayfinder’s predicted vessel position)

   • De-duplication: A new notification will only be sent when the time range for an alert does not overlap by more than 50% with the existing notification

4. High Wave Alerts

   • Trigger: Weather forecast is updated (every 6 hours)
   • Condition: The vessel is expected to encounter wave height values that exceed the set threshold for a 6+ hr period in the next 72 hours (based on Wayfinder’s predicted vessel position)
   • De-duplication: A new notification will only be sent when the time range for an alert does not overlap by more than 50% with the existing notification
