The term 'Secure in the HARBOR' can be broken down into two parts: MOOR (4 letters) and HARBOR. Mooring is the process of securing a boat or ship to a dock, pier, or other stationary object in the water. This is done by tying the vessel to a mooring line, which is then attached to a mooring buoy or anchor. The HARBOR is the body of water where the boat is moored. It is usually a sheltered area that provides protection from storms and other weather conditions. By mooring a vessel in a HARBOR, it is kept safe and secure from the elements.
