Ideal for harsh marine environments
AIS chain support buoys feature a thermolaminated closed-cell polyethylene foam core and a high-performance polyurethane elastomer skin so they are suitable for all marine environments.
Prolonged lifespan
The skin can be reinforced with nylon or Kevlar to achieve optimum tear resistance. This prolongs the lifespan of the chain support buoys in harsh marine environments.
Damage control
A high impact absorption rate means damage to the buoy and infrastructure can be minimised. Available in a range of non-marking colours.
