Haosail supplies a range of Structural Rota Moulded and Elastomer Buoys for Storm and Cyclone Moorings and Aquaculture Grids. 

During the design phase buoyancy and structural strength are calculated through rigorous analysis and specified for ultimate performance. Our system of structural buoyancy has been accepted by our clients and local port authorities as the superior method in comparison to chain through and pennant buoys on mooring systems where tackle is attached beneath the buoy which can cause entanglement.  

Anchor pendant and support buoy sizes are normally expressed in terms of the reserve buoyancy rather than the physical dimension.The reserve buoyancy is equal to the weight of water displaced by the buoy when fully immersed less the buoy's weight in air.
