Nylon has unparalleled ability to stretch and soak up a fall but this comes at a price with respect to some of its other
properties, most noticeably nylon is gyroscopic and is affected by water. This will cause the rope to shrink along its length and become stiffer after soaking.
Some users will Pre-soak their Nylon 8-strand rope for two hours then dry it before first use. But this must be done with caution on double braid structure. If the cores shrink and the cover does not, then sheath slip can become a problem.
The difference between 3 Strand Nylon and 8 Strand Nylon is most apparent when its hauled on deck. Because of its construction, the 8 Strand Nylon will take up far less space than 3 Strand. It lays more compactly in your locker or bag and will use about half the space of the same amount of 3 Strand.
