As we near the end of the boating season for most of us, it is a good time to look over our dock and anchor lines to see what we need to replace next season.
Most boats use rope made of synthetic fibers. Nylon is the strongest and most elastic which makes it the line of choice for anchoring and for dock lines. The elasticity helps to absorb shock loads when the water is rough.
Polyester is nearly as strong but has less stretch or elasticity which makes it a good choice for rigging on a sailboat.
Polypropylene is less strong than either nylon or polyester, but its prime value is that it floats. This is the line of choice for ski lines and even towing small boats (dingy) since it is less likely to tangle with the propeller. It does deteriorate more from sunlight and is susceptible to chafe and abrasions.
Are you interested in joining a boating club on Grand Lake to have fun, plus the opportunity to take courses online or in the classroom to improve your boating skills and knowledge?
