Types of Rope
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. |
Construction
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. |
