In the bad old days, decks were full of wobbly, sheaved high-friction blocks and essentially one kind of cordage. Today, running rigging has attained full-system status, with its primary goal being friction abatement.
Various types of syntheticfiber cordage, with specific strength, stretch and creep characteristics, run through ultraslippery blocks and fairleads. Each line is aimed at the exact spot a team of ergonomics experts determined it should go. Even the halyard hardware that attaches the line to the head of a sail has been computer-modeled and scrutinized with finite element analysis. Soft shackles and strops, made from Dyneema fiber rope, are showing up in…
