Marking of waterways, canals, sandbanks and other maritime obstacles

The B7 type inland waterway buoy has been specially developed for various applications on inland waterways. It is especially suitable for use on rivers with high flow rates of more than 3 m/s.

Due to its low mass only a relatively light anchorage is necessary. This makes the buoy easy to handle and therefore also ideally suited for temporary markings.

The floating body is made of polyethylene, is produced by rotational moulding and is foamed with PUR. The floating body is durable, colour-fast and therefore almost maintenance-free. The buoy can be supplied in standard IALA colour of red, yellow and green.

A ballast weight is attached to the lower part of the floating body. The inland waterway buoy B7 is supplied with a lifting eye and an adjustable anchor plate. Both are made of hot-dip galvanised steel. A radar reflector made of aluminium is integrated in the upper part of the buoy.
