How did we determine that the Ø 21 cm and 62 cm long inflatable fender was the perfect fit for a 10 meter boat? How many fenders will be required to securely protect the side of such a boat? To do this, you will have to perform a series of simple arithmetic operations, which are based on conditions developed in marine practice.

  1. To calculate the required fender diameter suitable for a boat of a certain length, it should be assumed that for every 120 cm of this length there should be 2.5 fender diameters. Let's substitute the numbers: 1000:120x2.5=20.8 cm. It turns out that we even have a small margin.
  2. To determine the required number of fenders on one side, we proceed from the fact that for every 2.5-3 meters of the length of the boat there should be 1 fender. That is, for a boat with a length of 10 meters on each side, you should buy 4 inflatable fenders Ø 21 cm.
  3. The length of the damper is important, since the area of contact with the quay wall or the side of another vessel depends on it. The larger this area, the weaker the impact force on each point of this protected area.

The listed price of inflatable fenders Ø 21 cm with double eye does not include fixing cables - you need to buy them separately.
