Fendercare Marine's navigation buoys are cost-effective, reliable and highly visible, offering long-term, dependable marks for a wide range of offshore applications.
Made from UV stabilised polyethylene, our range of navigation buoys are protected from the long-term degrading effects of naturally occurring radiation. Rotationally moulded for a seamless finish, these essentially stress-free one-piece navigational aids provide increased life functionality at lower prices.
Virtually maintenance free navigation buoys:
Requiring virtually no maintenance due to the manufacturing process, they have a life-expectancy of up to 20 years.
Where applicable, buoys are available with a choice of stainless or galvanised steel, and unique foam sandwich construction techniques offer exceptionally high strength to weight ratio.
Guardian navigation buoy

GRP minor light towers
Fendercare Marine manufacture a range of minor light towers that are constructed using modular sections to enable easy transportation and assembly at remote locations.
Fendercare Marine's minor light towers have the following features:
- Modular construction manufactured with a UV stabilised isophthalic gelcoat and resin, at a minimum thickness of 8mm, requiring little maintenance
- A range of tower heights available up to 15m
- The towers are locally reinforced by way of the flanges to produce a design of immense strength, allowing them to withstand gale force winds
- Access to the door section is via an external ladder. The ladder is removable to minimise theft or vandalism. Access to the lantern is via an internal ladder at the top. The top platform is fitted with guard rails to enable safe access to the lantern for maintenance purposes
- The towers can be fitted with stainless steel frames to support solar panels
- Each tower is supplied complete with lifting davit kit for on-site assembly
- The batteries can be stowed either at door level or at ground level within the cone section
- Colours are in accordance with IALA marking standards towers have been certified to withstand winds of up to 56m per second (125mph)
- A comprehensive range of lighting systems are available

Lite and super lite buoys
Whether configured as navigational marks in accordance with IALA guidelines or fitted out as databuoys, the largest buoys Fendercare Marine supplies offer outstanding durability and stability and are in service in some of the world's most challenging environments.
Our lite and super lite buoys are fully modular and the superstructure is engineered to both minimise windage and to accept large equipment packages. The flexibility of our technology allows us to adopt a ‘blank page’ approach with users who are looking to achieve a step change in the efficiency of their buoy operations or to incorporate very specific design features.
