Saltwater and dirt tears away at the fibres of the rope, shortening their lifespan. ‘Salty ropes’ are damp, thus collect more dirt. Ropes aren’t cheap and so proper maintenance will ensure you get the maximum performance out of your ropes.
Cleaning lines isn’t only a matter of cosmetics; clean ropes are easier to handle. This is especially the case for overworked ropes such as genoa and mainsheets. As a minimum, ropes should be cleaned properly at least once a year, at the end of the season.
