Sea route calculator

A very quick sea route calculator showing you the distance in nautical miles from any of the vessels AIS position to any port. Find the shortest route, ETA, days in sea, bunker ports along the route and estimated bunker consumption.  Save and share the routes.

Add ECA, SECA zones, (IMO and local zones), daily updated marine weather, piracy info and sea ice conditions to your route.

Calculate from a port, to any ports, with several port options or consecutive ports.

A very quick sea route calculator for laptops and mobiles

The sea route calculator is available in both products; ShipAtlas and ShipIntel. It will give you the shortest route from any vessel's AIS position in the map to any port or combination of ports, and find the distance, time and ETA. You can also route between ports. If you want to change the route on web; click and drag the route (same as you do in Google maps), and the route will quickly be re-calculated.

Why use this Sea Route Calculator?

The technology
Since there are no roads at sea, we have been using many different technologies while developing the Sea Route Calculator. We have created a network of triangles, visibility graphs, machine learning and other technologies. Then we have added information about canals and straits constrains to avoid routing vessels through canals if they are too large for the canal constrains. We have also added AIS tracks for different type and size of vessels to find where the different type of vessels have been sailing in the past.

Thus this Sea Route Planner is not a navigational tool for navigators.

The pitch
Might be the only sea route calculator able to route from any vessel's AIS position to any port on mobile and web super quickly and accurate FOR FREE and gives you the ETA, days at sea and bunker consumption.

You can compare the ShipAtlas sea route calculator with any other sea route calculators there are.

You can add bunker ports available along the route, find canal constrains and do consecutive sea routes.

You can route several vessels to one port, and find when they will arrive (ETA), and you can find alternative routes for one vessel to reach a specific port. You can save sea routes.

We will continue to invest in the sea route calculator since a sea route should be one of the backbone features in any maritime software.

Mobile and laptop
Use the sea route calculator from your laptop or mobile device and find time in sea, ETA first port, distance in nautical miles, bunker consumption, from any of the vessels AIS position. Turn on the marine weather forecast layer if you want to estimate delay due to bad weather. The weather is updated every 24th hour with a 15 days forecast. Turn on the ECA / SECA zone layer and find the bunker consumption.

The sea route calculator is excellent for cases such as: your vessel is en route to Tubarao, and your broker asks if your vessel can go to Madre de Deus instead and when she will arrive.

You can calculate the sea distance from any of the vessel’s position to any ports to find the deviation time from the vessels existing position, and the ETA to the possible new destination. Click on the vessel and the sea route calculator icon on the vessel card. On web you can click and drag the line to add waypoints or alternative routes (just as you do in Google maps).

Combine layers of information with the sea route calculator

You can add the layers of information you prefer like, and here are some of the layers you can combine with the Sea Route Calculator: 

Click on the layers you add and find detailed information about the specific layer.

The Sea Route Calculator is a backbone of our software products


We have a dedicated team working with the sea route calculation so while you are getting familiar with the sea route calculator, we will continue improving it and make it even smarter. We will add more features and layers of information to solve more user cases, and we will make sure it is super responsive on all your devices.
