Normally customer will choose the suitable marine boat launching airbags according the layers of the Marine Air Bags  , just give below an example .


4-layer bags that are 1.5m dia x 15m long contain a rubber content that is not less than 51%. The airbags can safely hold 156-tons with a safe working pressure of 0.08MPa while rolling. When standing still the highest lifting pressure is 0.10MPa while holding 194-tons.


6-layer bags that are 1.5m dia x 15m long contain a rubber content that is not less than 51%. The different cord layers launching airbags can safely hold 234-tons with a safe working pressure of 0.12MPa while rolling. When standing still the highest lifting pressure is 0.14MPa while holding 272-tons.
