Create your decision-making maritime map

There are more than 85.000 vessels in our Vessel Center and 5.200 ports in the Port Center. It is a lot of data!

In order to make it easier and more accessible, you can now adjust the marine map to your needs and apply filters and layers with information to have the better overview of the market and weather conditions.

Maps have been one of the most important humans inventions. People have, for decades, created and used maps in order to define, explain and navigate their way through the world.

This article will go through the icons in the right menu in ShipAtlas, where you can choose and add various layers to your map. You can apply one or more map layers simultaneously - create your own map according to your preferences.

Choose your map style

We recommend you to start with choosing a map style. You can find its icon on the right side - the "Map stiles and layers".

Here, you can choose your map style.

As you could see above, you can choose between three different map styles: "Light", "Dark" or "Satellite".

We talked about it shortly in the Main menu and navigation article - you might check out this guide in order lo learn more about vessel and port icons on the map.

Add vessels to the map (Vessel segments and lists)

Being able to see real-time AIS positions and vessel data is very important for the accuracy of your decision-making.


Choose what vessels you would like to track on your map - it may be certain vessel segments (like Tankers, Panamax) or maybe Vessel lists (maybe Mayersk vessels or your fleet). Add or remove sub segments from your map any time you want, combine them together or turn off everything and work with just one vessel.

Let's say, you have selected dry cargo vessels, but you also wish to view the tanker vessels. Then you can switch between these segments or apply them to the map them at the same time.

If you rest the mouse pointer on any vessel, you can see her name, sub-segment and some basic info about the ship. If you would like to access more info or check the Vessel Questionnaire, then you should click on the vessel.

Note, that if you are using ShipAtlas on your mobile, select the vessel segment and sub-segments from the bottom menu.

You can change the colors on the sub-segments and segments. Just click on the color dot and choose the color you like.

Add Vessel Lists and Port Lists

Go to the right menu again and choose the "My lists" icon. Here you will find Vessel Lists and Port Lists if you have created some of them before. Now you can add them to the map.


The vessels from your lists will be marked with a circle. The ports will be marked with a square. We talked about icons on the map in this article.

Choose the lists of ports or vessels matching your criteria and then add them to the map.

Add economical zones

Charter parties have clauses allocating risks when navigating in areas with changing seasons and potential ice. CP clauses refer to cargo intake, loading dates and INL for insurance coverage and the vessels are classed according to the classification companies requirements.

Let's say you are heading towards the winter and you can't remember when the load line zones change, or where the Polar Code applies. With ShipAtlas you can easy and quickly select and hide different type of information on the map.

LL - International Load Lines

Since these zones are changing during the year, you will be able to view the dates the zones are shifting by hover over (web) or by clicking one of the areas (mobile).

If you click at a vessel in the map, you will find information about her at the left side of the screen. If you want to view more, you can click on "more Details" button.

Read more about the Load Line convention in this article.

International Navigating Limits - INL

In 2000, the Institute of Chartered Underwriters in London revised the Institute Warranty Limits (IWL). Since 1st of November 2003, the limits have been referred to as the International Navigating Limits (INL). The INL define the geographical limits within which ships are able to operate without incurring additional insurance premium from hull and machinery and other relevant underwriters.

Operating outside the INL, in areas which can include significant hazards such as ice, could lead to damage to the ship and delay necessitated by repair.

You will find more information about International Navigating Limits (INL) in this article.

Polar codes

โ€‹IMO's International Code for Ships Operating in Polar Waters (Polar Code) is mandatory under both the International Convention for the Safety of Life at Sea (SOLAS) and the International Convention for the Prevention of Pollution from Ships (MARPOL). The Polar Code covers the full range of design, construction, equipment, operational, training, search and rescue and environmental protection matters relevant to ships operating in the inhospitable waters surrounding the two poles. The Polar Code entered into force on 1 January 2017.

You can select the Sea Ice map in Maritime Optima under "Map layers":

ECA /SECA Zones

In ShipAtlas you can check out different environmental zones with Global Sulphur regulations. This layer may be found in the right menu as well.

Check the weather in the port or in sea

You can check what is weather today in the certain region, or see a marine weather forecast for the next 7 days.

ShipAtlas lets you track Wind, Wave, Ocean currents, Ice and Precipitations.
If you wish to learn more about Weather Layers, you will find more information in the next articles.

Note, that weather filters in ShipAtlas are available only in the web-based app.

Be aware of the piracy incidents

In ShipAtlas you can see the Piracy map. Anti Shipping Activity Messengers are updated every 24 hours. If you click on the area where the piracy incident happened (it marked with red color), you will see details about the case.

Learn how you can track pirate activities on your map in the Piracy Maps guide.

Check the situation with congestion and canals

Congestion layer icon may be found in the left menu.

Check out the Congestion Layer - a real-time update for vessels waiting in the Suez and Panama canal

This tool will help you to access the real-time update for vessels waiting in the Suez or Panama canal (and some other locations) divided into segments and sub-segments.

You can also learn about canal restrictions. To access this information, choose a Canal icon from the Map layers (right menu).

See LOA, beam and draft constraints - it could help you to build the right sea route for your vessel.

Note, that congestion layer in ShipAtlas is available only in the web-based app.

Mobile App

If you are using ShipAtlas you also from the mobile app, you can follow the same order.

Use the bottom menu to add or change layers of information.


If you wish to add certain segments to your map, go to the bottom menu and choose vessel icon. Select "Lists" and switch between Vessel lists and Port list. Choose the lists you would like to add to the map.

Use different map styles and add various layers and zones to your map:

Note, that weather Layers and Congestion layer in ShipAtlas are available only in the web-based app.
