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

• High resistance to abrasion
• High energy absorption (up to 3.8 tons for F-13)
• Suitable for vessels up to 1500 tons (F-13)

F-series cylindrical balloons are essential for recreational vessels and are widely used by passenger ships, fishing boats, and commercial vessels.
