This highly visible yellow training mark is designed to last long. The mark consists of 3 separate parts: a solid outer, an inflatable inner bladder and a ballast bag.
The mark can be used anchored or as drifting mark. At the bottom you will find a big grab handle where you can easily fasten the mooring line.
The outer is made of thick 0.9 mm heavy duty fabric. On the top of the solid outer you will find an opening to insert the inflatable bladder. The opening has a velcro/buckle closure. On the side of the outer you will find two grab handles to make it easy to carry and to reposition the mark.
The inflatable bladder is made of polyurethane coated nylon and has a twist lock tube valve for quick inflation and deflation.
The mark has an internal ballast compartment to contain the separate ballast bag. The ballast compartment can be accessed through a velcro closure. The ballast bag has an easy to use lock buckle and can be filled with chain or stones.
