Sentinel is highly durable, has a long life span (up to 20 years) and so has reduced life-cycle costs. The neoprene rubber construction performs very well in extremes of temperature, being operational in temperature ranges from -40oC to +90oC without any deterioration. 

Sentinel boom can also be supplied with closed cell foam filling to provide a permanent or semi permanent boom ideal for protection of water intakes and high risk areas in ports and harbours. 

Sentinel can also be constructed in PU, which provides excellent performance, highly durable, cost effective boom for use in a range of applications. 

Fast inflation system

The boom is inflated by a low pressure, high volume inflator. 

Fast deflation system

Deflation valves enable fast deflation and recovery of the boom, saving valuable time on training exercises.

Enclosed tension member

Galvanised multi strand wire or chain maintains a perfect concave underwater profile for maximum oil containment. The wire is enclosed in a continuous pocket to prevent snagging and improve safety for operators. 


As an option, splashflaps can be incorporated to assist performance in choppy conditions to reduce splash over and negate the need for larger booms.
