Mooring rope is a type of rope used to secure a boat to a dock or other structure. The term 'HAWSER' (6 letters) is a large rope used for mooring, towing, or other purposes. A 'PAINTER' (7 letters) is a short rope attached to the bow of a boat, used for tying up or towing. Finally, a 'tye' (3 letters) is a loop or knot in a rope used to secure it to another object. All three terms are related to mooring rope and are commonly used when securing a boat.
