A quick to use sea route calculator

A smart sea route calculator for laptops and mobiles with ECA, SECA zones, (IMO and local zones), daily updated marine weather, piracy info and sea ice conditions.

Calculate the shortest route / distance, time, bunker consumptions and carbon emissions for any of the 85 000 vessels real-time AIS position.

Calculate from any of the vessels AIS position to any ports, or from any port-to-port or from vessel-to-vessel.

A smart sea route calculator for laptops and mobiles

The sea route calculator is available in both products; ShipAtlas and Maritime Optima Pro. It will give you the shortest route from any port to port, or from any vessel's position in the map to any port. 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 Maritime Optima's Sea Route Calculator?

Some might remember when Erik Loy Sr. launched the digital Dataloy distance table and the industry left the BP distance table book in the 90's in favour of the Dataloy's digital distance table. Today you will find many digital sea route calculators, so why use the Maritime Optima sea route calculator?

Since there are no roads at sea, we have been using many different technologies while developing the Sea Route Calculator. 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 added AIS tracks for different type and size of vessels to find where the different type of vessels have been sailing, we have created a network of triangles, visibility graphs, machine learning and other technologies.

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

Use the sea route calculator from your laptop or mobile device and find time, distance, bunker consumption and carbon emissions, from any vessel. If you want to check out the daily updated marine weather forecast to find if you should expect any delays due to bad weather, turn on the marine weather forecast layer. You can also find; the daily updated sea ice condition or piracy activities which we update every 24th hours, or you can add ECA/SECA and economical zones.

If you want to calculate the sea distance from any of the vessel’s position to any port to find the deviation time from the vessels existing position, just click on the vessel and choose the sea route calculator on the vessel card. On web you can click and drag the line to find the route you prefer (just as you do in Google maps).

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.

Combine layers of information with the sea route calculator

You can add the layers of information you prefer like the daily updated marine weather, daily updated piracy information, ECA / SECA zones (local and IMO defined zones) or switch between default maps and satellite mode.

Here are some of the layers you can combine with the Sea Route Calculator: 

Check deviation from existing position in time and distance

If your vessel is drifting for order (in image below: off WA), click on the vessel and add the possible load ports you consider (in image below: Salvador and Bonny), add weather (in image below: wind) and quickly find the ETA for your vessel in the different loading ports (Salvador and Richards Bay).

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.

You will find the Sea Route Calculator as a stand-alone feature, in the voyage calculations and as a part of the shipping market intelligence / analytics in combination with machine learning.
