The Seakeeping and Safety alerts feature can be found on the left side panel of Wayfinder.
Draft, Displacement, Metacentric height (GM), Roll period, and Overall length reflect the current state of the vessel. These values should ****be updated when the vessel is imminently departing or if these values change while underway.
Under each value, you can see the last time the value was changed and by whom - either by a user, a Sofar Operator, or by a recent vessel report.
An in-app notification to update Vessel Details will appear as an orange symbol next to the seakeeping icon on the left and will trigger when your vessel transitions to a new voyage. The notification will clear when any of the values are updated, or if noon reports update all of the values. As long as the notification is present, seakeeping alerts will not show along route, to prevent erroneous seakeeping alerts due to outdated values.
Synchronous rolling and parametric rolling are shown along your route, in accordance with IMO Guidance (Revised Guidance to the Master for Avoiding Dangerous Situations in Adverse Weather and Sea Conditions (MSC.1/Circ.1228; Jan. 2007)). Wayfinder predicts Parametric Roll, Synchronous Roll, High Wave attack and Broaching based vessel specific thresholds.
Each warning has a significant wave height threshold that will determine whether the warning is visualized along your route as "Low risk" or "High risk".
Please review, edit, and save your preferred significant wave height thresholds for each type of warning in the Seakeeping tab in Wayfinder. Click Save after making any changes, otherwise changes will disappear.
The seakeeping alerts will be shown along routes on the interface. Hover over the highlighted area on the route to see the type of alert and the associated weather conditions.
