What is the purpose of fenders on a boat?

The purpose of fenders on a boat is to provide cushioning and prevent damage during docking or mooring. When a boat comes alongside a dock or another vessel, fenders act as a buffer that absorbs impact, protecting the hull from scratches, dents, and other potential damage that could occur from contacting hard surfaces. By using fenders, boaters can ensure safer boarding and disembarking, as well as minimize wear and tear on both the boat and the structures they interact with. This is especially important in environments with currents or waves, where boats might move unpredictably against docks or other vessels.
