1200mm Diameter Fast Water Buoy Type SL-B1200-FW
The Sealite SL-B1200-FW is a large 1200mm dia. navigation buoy designed for rivers, ports and harbours and estuaries with fast flowing water current of up to 8 knots.
Designed using a traditional navigation buoy shape above the water line and incorporating the shape of a boat hull on the bottom, the SLB1200-FW remains extremely stable and buoyant in fast and rough conditions. Its unique design incorporating an integrated bow and keel, allows the SL-B1200-FW to create lift as the water flows underneath it, enabling the buoy to rise and sit higher on the surface of the water creating more stability and allowing it to support a heavier payload.

The single piece float section has a integrated 316-stainless steel tie -bar to provide exceptional strength and safe working load for lifting (one lifting eye) of 2300kgs.
The 1200mm buoy is rotationally moulded from UV-stabilised, virgin polyethylene to 9mm wall thickness to provide additional strength.
The fast water buoy comes in a range of IALA recommended configurations and colours for excellent visibility and is developed to support a variety of marine lanterns.
