Anchors and Cable
The weight of anchor you need depends on the length, breadth and depth of the vessel. Use approximately 6 metres of chain on the outer end of the anchor cable. The cable itself may be link chain, wire rope, manilla rope, other fibre rope of equal strength, or a combination of chain and rope.
The size and length of cable you need depends on the weight of the anchor. The table below provides some guidelines.
| Weight of main anchor (kilograms) | Minimum diameter of chain or wire rope (millimetres) | Minimum circumference of manilla or other rope (millimetres) | Length of cable (metres) | ||
|---|---|---|---|---|---|
| 1 or 2 anchors... | 45 | 9.5 | 64 | 55* | |
| 1 or 2 anchors... | 90 | 12.5 | 89 | 55* | |
| 1 or 2 anchors... | 135 | 14.0 | 102 | 82 | |
| 2 anchors... | 180 | 16.0 | 114 | 100 | |
| 2 anchors... | 230 | 17.5 | 127 | 137 | |
| 2 anchors... | 270 | 19.0 | 127 | 137 | |
| *If two anchors are carried, the total length of cable shall be increased to 82 metres. | |||||
