1500mm Diameter Navigation Buoy
Sealite’s SL-B1500 is an extremely robust, high visibility 1500mm diameter navigation buoy perfect for a variety of installations including inland waterways, harbour and coastal navaids.
The SL-B1500 has a one-piece, rotationally-moulded float section which incorporates an internal stainless steel brace that is linked between the lifting and mooring eyes. This brace ensures even stresses across the buoy during lifting, creating an incredibly robust AtoN with a service life of up to 20 years.
The top section of the buoy is also rotationally-moulded from UV-stabilised, virgin polyethylene, and can be fitted with top marks and lantern to suit any IALA recommended buoy configuration required. The buoy has direct lantern attachment points for a variety of Sealite solar lights.
Polyethylene buoys require minimal maintenance; they never have to be painted, and the polyethylene inhibits marine growth therefore increasing the interval between servicing.
The lightweight but strong polyethylene also means routine maintenance may be performed on site.
The SL-B1500 is environmentally-friendly and recyclable
