The maximum tensile strength is achieved by the two multiple solid ropes reinforced with arms. Tested for durability and flexibility in temperatures from -30°C to +50°C, these heavy-duty balloons feature:

• High abrasion resistance
• High energy absorption (up to 3.8 tons for F-13)
• Suitability for ships up to 1500 tons (F-13)
• Widely used by passenger ferries, fishing vessels, and commercial ships

These cylindrical balloons of the F series are essential for recreational boats.
