- UV resistance – UV‑stabilised nylon offers high resistance; many vendor spec sheets cite UV performance around 70% of the industry maximum.
- Abrasion resistance – a robust fibre and, in braided ropes, a tight outer cover create a hard‑wearing surface that endures rubbing against chain, rocks or deck fittings.
- Rot and chemical resistance – nylon’s low moisture uptake and synthetic polymer structure resist rotting in salty spray and generally withstand diesel and common cleaners (avoid strong acids or alkalis).
