As with most things in life before we can really start to understand pioneering, we need to understand the basic and why things work.

Ropes and their Care

Not so many years ago, any rope you used would have been either hemp (including manila) or sisal, produced from natural fibres. Today, we still have these ropes, and sisal is still the cheapest to buy, but there is now a range of ropes produced from synthetic fibres, which will often show greater advantage in use.

Of the natural fibres, manila is undoubtedly the finest, followed by hemp. Sisal is a good general purpose rope, but it deteriorates more rapidly than hemp or manila; it sinks in water; and when wet, looses some of its strength.

Of the ropes produced from “man-made” fibres, nylon is the best known. It is extremely strong and has considerable elasticity, making it ideal for shock loads. It offers less friction than other ropes, so that extra tucks are essential when knotting it, and it should never be allowed to run fast over, for example, rock edges as the heat from the friction may cause melting on the surface.

The size of ropes is normally quoted in terms of diameter, given in millimetres, and in most cases, rope is bought in coils of 220m, expressed as a mass. For example, a coil of 10mm rope would weight 15 kg, while a coil of 26mm rope would weigh 109 kg.

Most of the rope you will handle will be three-stranded, laid up right-handed. Generally, the strands are built up from yarns of the basic material in random lengths twisted together. Three-stranded rope laid up right-handed is often called “hawser-laid” rope.

Rope is expensive material and should be well looked after. New rope should be strained before use to remove its initial stretch. When not in use, all rope should be properly coiled and stored. Light ropes should be coiled on the floor, the operator standing with his back to the bulk of the rope, and hauling it up through his legs, and laying turns in a clockwise direction. The complete coil should be tied off with small stuff (sisal string) and hung up on a peg, clear of the ground.

Shorter lengths of light rope should be put together in bundles of ten ropes of equal length, and tied at each end with overhand knots.

Wet ropes are particularly susceptible to deterioration unless carefully and thoroughly dried out. The ropes should be coiled as described, in as large turns as possible, and hung in an even, moderate to cool temperature. Never dry them out by heat.

Some useful knots worth knowing

Barrel Hitch
This is the simplest and most effective way to sling a barrel in a vertical position. To tie it, place the barrel on the rope, bring the end and standing part to the top of the barrel and make a half-knot (fig 1). Open the half-knot and push the two parts outwards and over the edge of the barrel, as indicated by the arrows in fig 1. Bring up the end and standing part and make a bowline (fig 2) and your sling is complete.

Blackwall Hitch
A simple yet secure method of fastening a rope in a hook. It should only be used when the diameter of the rope is nearly enough to fill the mouth of the hook. The illustration shows clearly how it is made. The rope can be taken round again to get two bights in the mouth of the hook and so forming a Double Blackwall Hitch, but it is doubtful whether any advantage is gained.

The Carrick Bend / The Josephine Knot
This is probably the finest end you can make: it is the nearest approach to the perfect knot. Its only fault is that it is rather bulky. It is used mainly for hawsers and heavy ropes but it is also widely used as a decorative knot. It is important to remember that, for the knot to be correct, the two ends must emerge from the knot at diagonally opposite points. To tie it, make a single turn in the end of tone rope, the end passing under the standing part. Lay the other rope under the turn (18), take the end round over the standing part of the first rope, under the end, down into the turn, under its own part and up and out of the knot, ie. Carefully follow the arrows in fig 18 to arrive at fig 19. There are two ways of completing the knot: everything may be drawn up snugly when you will have a solid, squarish knot as in fig 21, or it can be closed and the ends seized to the standing parts (20) which is the method most used at sea. Ashley states it is possible the nearest thing we have to a perfect bend. It does not easily slip, not even if the rope is wet. And it is always easy to untie, also after a heavy load. If used as a Hawser bend in heavy material it is always seized and parcelled to save wear.
