  • Features

    Four (4) Tough Polyethylene Float Sections
    These form the heart of the buoy. Colour pigment is compounded into virgin polyethylene which is further enhanced by Tideland’s unique, UV18 stabilizer. Results are outstanding in terms of colour retention and physical strength that resists damage. Unique mould design and control process ensure a homogeneous profile with an increased thickness in high stress areas. This polyethylene also assists in repelling marine growth.

    A Single Counter Weight
    Manufactured from cast steel and fixed to the base by a strong, yet simple, technique. This allows counterweight attachment within minutes during buoy deployment.

    Galvanised Steel Hull Frame
    Fitted with four lifting eyes and two mooring eyes. The design allows each of the hull sections to be easily fitted and quickly replaced if damaged. As an option, the hull frame is also available in stainless steel.

    Top Superstructure comprises several options including:

    •  A simple galvanized frame with an integral ladder rated for over 200kgs
    •  A galvanized steel frame clad in polyethylene panels to improve day time visibility
    •  A complete polyethylene tower
    • There are also pre-designed holes for mounting solar panels and battery boxes in the base. Options include painting the superstructure to match hull float sections, as well as a stainless steel version. The superstructure can be removed from the core for maintenance purposes.

    Day marks, top marks, solar panels, battery box and battery pack, AIS AtoN, racon,along with a buoy monitoring system utilising VHF, GSM, or satellite communication links.
