# About Dataloy Distances

**Dataloy Distances** allows port and routing point searches when building sailing routes and is available to commercial and non-commercial users. Sailing routes are presented graphically on a map and are based on an analysis of possible routing options.

Search for the ports you want your route to consist of in the "Port" field and add them one by one. As you add ports, the route will be populated and visualised on the map.&#x20;

Rearrange the order of the port calls by dragging the port call to the desired sequence.&#x20;
