The Seakeeping and Safety alerts feature can be found on the left side panel of Wayfinder.
Draft, Displacement, Metacentric height (GM), and Roll period, 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.
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.
Encounter wave alert thresholds can be set in the seakeeping tab, along with other seakeeping alert thresholds.
The thresholds correspond to the following angles of attack (symmetrically on either side of the ship):
Head: 0 - 22.5° from the bow
Bow: 22.5 - 67.5°
Beam: 67.5 - 112.5°
Quartering: 112.5 - 157.5°
Following: 157.5 - 180°
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.
You’ll also see encounter wave alert arrows in daily guidance PDFs.
