 Ultrahigh Molecular Weight Polyethylene Isolated Danger Mark Buoy
JRB-IDMB show where there is an isolated danger that has navigable water all round it (for exmaple, an isolated shoal, rock or wreck) - but don't pass too close. Isolated danger marks are black with 1 or more red horizontal bands and 2 spheres as the top mark. At night, the white light flashes in groups of 2.  proven  its superior performance in many countries around the world for long-range river and sea navigation. All our buoys are in line with IALA guideline and recommendation. We can also supply the certificate of CCS.

The base is moulded in one-piece, strong, coloured, durable polyethylene – filled with closed-cell polyurethane and UV-stabilised for resistance to sunlight.

The strong, lightweight polyethylene buoy top is moulded in standard IALA high visibility colours and shapes to suit arange of installation requirements.
