Tug Boat Rubber Fenders are often used on the bow and stern of tugs as primary pushing fenders. Their circular shape makes them ideal when working with large bow flares such as container ships, but they are equally suited to pushing flat sided vessels. Tugboat Rubber Fenders are fitted to the tug hull with a longitudinal chain running down the fender bore. On larger fenders, these chains are supplemented by circumferential restraints – either sleeved chains or webbing straps – which sit in special grooves moulded into the fender body at intervals along its length. The ends of the Tugboat Rubber Fenders can be tapered to help fair them into the hull.
