Synthetic
|
||
Nylon | Strongest of all ropes in common use (when dry). Resistant to abrasion. Will stretch so absorbs shock loads. Good for tow lines, anchor warps and dock lines. | |
Polyester | Stronger than nylon when wet. Low stretch with good abrasion and chemical resistance. Used for running rigging. | |
Polypropylene | Not as strong as other synthetic fibres. Floats and does not absorb water. Excellent chemical resistance but deteriorates in sunlight. Used for rescue lines. | |
Polyethylene | Similar to polypropylene. Deteriorates in sunlight, subject to chafe. Floats in water. Used for water-ski ropes and within the fishing industry. |
Natural
|

Manila | Strong, low stretch and very resistant to sunlight. Holds knots well. Needs to be stored cool and dry. Used for sustained loads and decorative ropework. | |
Sisal | Similar to manila but not as strong. Commonly used for lashings and tie-downs. |
Twisted
|
Most commonly 3-strand with a right hand twist. Have a preferred direction for coiling. | |
Braided
|
Inherently low stretch, soft feel and low friction. Majority consist of outer cover and inner core. More difficult to splice. |
