ShipAtlas always chooses the shortest route for you. Yet, sometimes it is not the shortest route we want. That is why ShipAtlas allows you to edit the original route suggested for your vessel. This is possible both with the FREE, Standard, and Premium plans, but with the premium plan ShipAtlas allows you to create duplicates of your route instead of having to make adjustments to the original one.


For those who have read our previous guides and know how to make adjustments and duplicates to their routes, scroll down to "How to Optimize Your Routes" to learn more about the route created between several ports.

How to Make Adjustments to Your Route

Hold the line and drag it to the place you want to be included in your new route. By doing this you are adding a new point in your route which will appear in the sea route calculator.

An example of changing the suggested route from ShipAtlas with the FREE or Standard plan:

If you have the Premium Plan, however, there are more options for you within the sea route calculator.

How to Duplicate Your Route

Step 1

You can duplicate the route by clicking on the "Duplicate" button on your card.

Step 2

When you edit the duplicate you will be able to see the original ShipAtlas route in the background of your new route.

Step 3

Save your new route or update your old one by clicking on the "Save routes" button at the lower-left corner of your screen. If it is new, give your route a name and save it by clicking the "Done" button.

How to Optimize Your Routes

Comparing Routes with a Different Order

Changing the order of your route is easy, just click and drag on the ports in your sea route calculation to change the order of ports in the calculation.

Comparing Routes with Different Destinations

If you want to compare the route to another one with a different port, just change the destination in the duplicated journey. You now have two cards, that you can alternate clicking on, to compare distance and time to a or several ports. The cards only show the ETA to the first port, and if you want to see the ETA to each port on the journey you have to click on "More Details" at the top of your route calculator.

You can also use the duplicate function as much as you would like.

Comparing Different Route Alternatives

If you create a route from a vessel to a port where there are different alternative routes to the port, ShipAtlas will choose the shorter route. The alternative route will also be shown on the map. If the shortest route is via a canal, which most of them are, you will see a warning in the route calculator that it includes a canal, and give you the option of avoiding the canal.

If you want to compare the two routes, duplicate the first card and then choose to avoid the canal on the duplicated card. Remember that you can see the details of each voyage by clicking "More Details" at the top of the route calculator.
