Boating & Jetski Barriers

Prevent entry from marine traffic.

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 for safety reasons.

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 booms are now part of our portfolio. The Bolina Hemi Ball Booms are highly visible because of their spherical shape, allowing them to float higher on water.

We can provide the full scope of supply, installation and maintenance.

Demarcation Barriers
ProductsStandard Demarcation BarriersBolina Hemi Ball Booms
ApplicationsSolid line barrier manufactured from hard PVC with high tension internal rope. High profile floats for better visibility. Also suitable in wave environments. Highly visible line on the water, marking a demarcation zone. Ideal for nearshore applications, inland waterways, marinas, private water bodies and nature reserves.

Standard Demarcation Barriers


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.

Bolina Hemi Ball Booms

Ball Float Demarcation Barriers

The Bolina Hemi Ball Booms (HBB-400) consist of 2 hemispherical rotomoulded sections, manufactured from UV stabilized polyethylene.

They are extremely tough and robust, ideal for beach markers, small channel identifiers and other uses where a floating line of demarcation is required.
