What is a one-sentence summary of the following article?
Cleats are T-shaped metal hardware that are usually placed on the sides of the boat, close to the edge. There will also be cleats on the sides of the dock. The dock lines on the boat must be attached to the cleats to the dock to keep the boat in place. Most boats will have cleats on the bow, stern, and sides for docking. If your boat does not have cleats, you can buy them at your local boating store or online and attach them to your boat. Pilings are long pieces of timber or metal that have a cleat on them. They are often attached to a pier or dock. You will need to use dock lines and knots to secure your boat to a piling. Pilings are also sometimes used if you plan to dock your boat for several weeks or months, as they can keep it secure for a long period of time. Fenders are usually made of foam or inflatable rubber. They attach to the front and sides of your boat so it does not hit the pier or dock. They are ideal if you are tying up your boat in a busy dock or want to protect the sides from damage when it is tied up. You can find fenders at your local boating store or online. If you decide to use fenders, attach them to your boat using the ties on the fenders. Leave them on, hanging inside the boat, until it is time to dock. Then, place them on the outside of the boat before you set up the dock lines.
Check that your boat has cleats on all sides. Use pilings if there are no cleats on the dock. Get fenders to protect your boat from scratches and damage.
