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.
