Using Lines and Knots
All boat operators routinely use lines or ropes to secure the boat to a dock or attach to a mooring post or buoy. Lines can be made of either natural or synthetic material. Nylon ropes are good for use with propeller-driven boats since they will sink, not float. However, synthetic ropes have a smoother and more slippery surface, making it easier for a knot to come undone. Regardless of the type(s) of lines or ropes you use, make sure they are well-maintained. Store ropes dry, clean, coiled and free of kinks.
Tying knots is an important skill for boat operators that improves with practice. Knowing how to securely tie knots will not only keep your boat and equipment secure when tying off to piers and mooring buoys, but may also be an emergency procedure if you are forced to anchor in open water during bad weather.
