The maximum resistance to rupture is achieved through two multiple solid ropes reinforced with brackets. Tested for durability and flexibility at 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 vessels up to 1500 tons (F-13)

The cylindrical balloons of the F series are essential for recreational boats and are widely used by coastal vessels, fishing boats, and commercial ships.
