Rubber side fender. Made from exceptionally hard wearing recycled PVC. The side fender attaches to the canal narrowboat or barge by a single rope that passes right through the tube.
The rope is knotted above and below the tube and a plastic washer on the top/bottom prevents pull through.
There is enough rope to attach these rubber side fenders at gunnel or handrail level. To avoid any losses we advise that you to sail with side fenders up, deploying them only for mooring.
