Question 3

How do I edit a route?

Henri · Accepted Answer

Open the left sidebar and select the “Routes” section. Display the route on the map by activating the “eye” symbol, then tap or right-click (depending on your device) on any part of the route. In the menu that appears, choose the option “Edit route”.

You can then drag points on the map to move them, add new ones by tapping on a segment of the route, and edit or delete any existing route point.

Question 4

What are the wave patterns or sea conditions?

Henri · Accepted Answer

These models provide a simplified description of the sea state.
In short, they include the significant height of the total sea, its period, its direction, as well as the same information for the wind sea.

They are mainly used in routing when conditions are challenging.

Global Models

GFS 0.25° (28 km), 0.5° (56 km), 1° (111 km), 2° (222 km)
