I know conventional wisdom decrees that running rigging use polyester
cordage and anchor line use nylon. The nylon is said to stretch more, and
thus take up shock loads more readily. Polyester, on the other hand,
stretches less and is said to make setting the sails easier. I can
understand this for racing purposes, but wouldn't the same tolerance to
shock load be a blessing in a cruising boat where resilience of the rig is
of ultimate importance?
