Note: Manila rope, the standard for many years is not as strong as some ropes
made of synthetic materials. For mooring, its ability to stretch is an advantage, but
it tends to shrink whenever it gets wet. Nylon rope is strong and elastic. Because of
its elasticity, it works well for mooring lines and anchor lines. Rope made of high
tensile strength polyester fibers like Dacron™ is just about as strong as nylon rope,
but it does not stretch. Kevlar rope is strong and does not stretch, but it is quite
expensive. Polypropolene rope tends to deteriorate rapidly when it is exposed to
sun light. Because it floats, it is well-suited for use as a tow rope for water skiing.
Use for other nautical purposes is not recommended.
