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. That's why we have built a "Map tool box" where you can create your personalized map.

In Maritime Optima you can add and remove layers of information as you prefer.

LL - International Load Lines

Since these zones are changes 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 point at a vessel in the map, you will find information about her at the bottom of the screen. If you want to view more, you can drag the info box up.

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.

Polar codes

​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 Polar code in Maritime Optima under "Map layers":


In Maritime Optima you can add one or several map layers at the same time.
