Navigational route signage

Vessels sailing on the Vistula use the designated navigational route. When sailing downriver in Warsaw, that is with the current, one should pass with the starboard red beacons or buoys in the shape of a cylinder, and the stern past green beacons in the shape of a cone. These beacons mark the width of the navigable route along which it is safe to sail. These are examples of floating navigational signs. There are also navigational signs on land; in the case of the Vistula’s Warsaw stretch there are for example, no standing signs, no anchoring signs (such as at the mouth of the waters – at Gruba Kaśka and Chudy Wojteks, near the port’s entrance), information signs, such as the crossing of overhead cables with the river, e.g. the two cables in the stretch of Tarchomin Vistula, or the place where the main navigational route joins with a side route, as for example Vistula with Żerań Canal. Examples of signs with bans and recommendations can be found on Warsaw’s bridges, and thanks to those signs we know under which span of a given bridge we should sail and how wide the safe crossing is under the bridge.

The chapter of navigational knowledge, which is a collection of information about river routes, essential for safe sailing on rivers, is called river pilotage.

The project ‘Protecting the habitats of priority bird species of the Vistula Valley under conditions of intensive pressure of the Warsaw agglomeration’ (wislawarszawska.pl) has received a grant from the Financial Instrument for the Environment (LIFE+) and from the National Fund for Environmental Protection and Water Management.
