It is important to deepen your knowledge about the product you use; therefore, in this guide you can find out more about what each layer represents and means!

Here are the 10 layers that are described in this guide:

Note that by choosing satellite map style, map layers are not available. In addition, you can add multiple map layers at a time!

The Purpose of Map Layers

ECA/SECA

ECA/SECA stands for Emission Control Area/Sulphur Emission Control Area.

As of 1st January 2020, International Maritime Organization (IMO) enforced the Sulphur Emission Regulations which require that all ships shall reduce their Sulphur emissions from 3,5 % to 0,5% in all of the world's seas.

The implementation of the global 0.50% Sulphur limit has not changed the requirements applicable to the four ECAs designated under Regulation 14 of MARPOL Annex VI. So in the North American, US Caribbean, the North Sea, and the Baltic 0,10% Sulphur limit continues to apply. In addition, several countries have implemented even stronger limits in their ECA/SECA zones. To find the applicable regulation just click on the highlighted sone to get the specific requirements.

INL

The International Navigating Limits (INL) define the geographical limits within which ships can operate without incurring additional insurance premiums from hull and machinery and other relevant underwriters.

Note that you can click on each area to get specific information about the limits.

Polar

Clicking on this icon highlights the area covered by IMO´s polar water codes

which set rules for ships operating in this area.

Sea Ice

Clicking this icon will give you the limits of the current sea ice.

It is updated from NSIDC daily.

Canals

Clicking canals highlights important canals on the map.

When clicking the highlighted canal in the map you will see the applicable restrictions.

EEZ

This shows you the Exclusive Economic Zone at sea of each country.

Load Lines

Clicking the applicable load line zone gives you the dates when

there are deadweight restrictions in each zone.

Anti Shipping Activity

Turning on this layer will highlight areas where anti-shipping incidents have taken place in the last 365 days. Clicking on each highlight will give you a description of the incident.

High-Risk & War Zones

Enabling this layer will illuminate regions that pose a high risk for navigation or are designated as conflict zones.

Wind Farms

Enabling this layer will illuminate wind farms located on the water.
