The heavy-duty ship balloons feature maximum resistance to rupture thanks to the two multiple solid ropes reinforced with arms. They are tested for durability and flexibility in temperatures ranging from -30°C to +50°C. These balloons offer high abrasion resistance and an energy absorption capacity of up to 3.8 tons for F-13, making them suitable for ships up to 1500 tons (F-13).

In addition to their use on recreational boats, cylindrical balloons of the F series are widely used on passenger ships, fishing vessels, and commercial ships.
