Captains all over the world buy fenders or try to make their own to place them as a protective buffer between their boat's hull and the pier walls. This protects against friction and damage to the side coating, and can also protect against impacts at the moment of mooring itself - the inertia of the course or a strong wave can crush the yacht into the pier and leave a dent.
Many people prefer tied fenders because they do not require rigid fixation, they are easy to move and to quickly attach, and inflatable ones are also light in weight. They are often selected, including by color and design, to emphasize the style of their yacht.
The required minimum size is usually calculated based on the formula 2.5 cm fender diameter per 120 cm yacht length. Extreme situations, not equipped berths and docking in bays with strong tidal waves and rough seas, of course, require larger fenders.
