Although it is quite strong it does lose about 15% of its strength when wet. In most cases, this is not significant, but it should be factored into the rope-buying decision for applications where the rope will be exposed to water.
It should also be noted that it is very dense and sinks in water.
Nylon is the best choice of rope for many applications.
This includes marine, general purpose, and towing. It is very strong, but perhaps more importantly highly UV and abrasion resistant, so it lasts a long time.
Nylon ropes excel at both of these tasks.
Braided ropes are recommended for pulling heavy loads as it does not coil and unravel like 3 strand ropes when pulled by strong force .
Use braided ropes for pulleys and similar usage.
