This type of fenders are generally produced to prevent ships to be harmed when they come side by side and touch each other.
 Also, they can be used as marine/port fenders, that is to say, they can absorb ship's berthing force when they are located properly on the pier. Reaction values can change dependly on the hardness of rubber.
 This system is pretty practical. In any case, using these fenders in the marines are much more efficient. Because, being in the move all the time on the ships can damage them. However, hanging type fenders are easy to use and practical. These fenders' empty inside but their perimeters are pretty thick. So that, their performance and absorbation values are relavently higher. They stretch perfrctly. In the list below, it is possible to see the types ans performances. The absorbation might be too much for small boats.
