Sling Type Pneumatic Fender is common type of Pneumatic Rubber Fenders. It is designed without chain and Tyre net. So its advantage is lower weight than traditional chain and tyre net fenders. Meanwhile, Sling type pneumatic fender commonly used for some small and medium size vessels.
The ratio of the length and breadth can differ quite dramatically depending on the type of vessel. Common values:
A larger L/B value is favorable for speed, but unfavorable for manoeuvrability.
The length/depth-ratio. The customary values for L/D varies between 10 and 15. This relation plays a role in the determination of the freeboard and the longitudinal strength.
The breadth/draught -ratio, varies between 2.3-4.5. A larger breadth in relation to the draught (a larger B/T value) gives a greater initial stability.
The breadth / depth ratio, varies between 1.3 and 2. If this value becomes larger, it will have an unfavorable effect on the stability (because the deck will be flooded when the vessel has an inclination) and on the strength.
