ECA / SECA zones on the map

ECA / SECA zones are emission-control areas where sulphur-in-fuel limits apply. On the rynda map you can turn them on as a separate layer.

How to show the zones

1. Open the Ports Map.
2. In the left rail, open the "Navigational environment" group and switch on "ECA / SECA zones" (on a phone: Layers → Navigational environment).
3. The emission-control-area boundaries appear on the map.

Why it helps

• Plan bunkering against sulphur limits.
• See where a route crosses into a restricted zone.

Current as of 2026 — environmental rules directly drive fuel and routing choices.
