Voyage Planning: Display & Avoid Load Line Zones

How load line zones are displayed on the Voyage Planner routing map, and how the routing engine accounts for them automatically when generating plans.

Question: How do I see load line zones on the routing map, and does the router account for them automatically?

Load line zones appear as a dedicated map layer in the Voyage Planner, so you can see them directly on the routing map instead of cross-checking external charts.

  • The routing engine accounts for load line restrictions automatically when generating voyage plans.

  • If a vessel's origin, destination, or a waypoint falls inside a restricted zone, the system handles this without failing the planning flow.

Background: load line regulations define how deeply a vessel can operate at a given draft, depending on season and sailing region. This layer brings that regulatory context directly into your planning workflow rather than requiring a separate manual check.
