Chart a corridor

Name two ports. Style and vessel sit under the box.Ask for a sea route the way you would in chat. Ports in the prompt; map style, vessel, and overlays as tools underneath.

Describe a corridor. Set map style and vessel below — or leave them on Auto.

Plan · Compare · Verify

1 · Plan
Choose an origin and destination port — search by name or UN/LOCODE, or tap the map.
2 · Compare
Review corridor distance, transit, and modeled risk side by side before diving into detail.
3 · Verify
Inspect assumptions, sources, freshness, and limitations — then validate with operational tools.

Worked example

Rotterdam → Singapore

Illustrative shortest network path ≈ 8,400 nm · ~25 days transit · modeled risk in the High band — alternatives diverge via Cape or constraint avoidance. Open the planner to recompute live.
