Product Description Polyurethane Navigation Buoy The Polyurethane navigation buoy is moulded from polyurethane elastomer with high-quality fluorocarbon materials exterior. The buoy is enhanced by internal stainless steel skeletons. All materials employed are highly resistant to severe marine environmental conditions.

The buoy is filled with closed-cell flexible foam, which will prevent the ingress of moisture in the unlikely event of damage. The lightweight buoy is capable of supporting substantial loads. The buoy is designed to provide an excellent buoyancy. Marking panelings are filled to the outside of the tower section to create a large colored visual area for navaid recognition. A large counterweight offers exceptional stability in a variety of exposed regions .

The polyurethane navigation buoy can be supplied in all IALA colors.
