Marine Demarcation

Boating & Jetski Barriers

Creating an enclosed safety zone - Used to restrict marine traffic or designate a protected or restricted area.

Boating and jetski barriers are primarily used in marinas, waterways, open beaches and any other area requiring demarcation to restrict marine traffic or designate a protected or restricted zone.

They can be custom made and are generally made up of a combination of small floats and larger marker buoys connected by high tension lines. In areas of high marine traffic, the barriers are enhanced by larger navigation buoys, to ensure easy visual identification of the barrier.

Bolina demarcation barriers are now also part of our portfolio. These robust barriers are the preferred choice for both British Waterways and the Environment Agency who control the navigable waterways within the United Kingdom - similar authorities overseas have followed their lead.

We can provide the full scope of supply, installation and maintenance. Get in touch to know more!

Standard demarcation barriers are highly durable, suitable for long-term use and have a broad range of applications in different marine environments.

Their hydro- and aerodynamic design gives them exceptional floating stability and maximum endurance in even the most extreme weather conditions.

To improve identification of the barriers, navigation buoys and lights can be provided to ensure clear demarcation.
