Ashley

Last week I posted our first Official Blog Puzzle:

“The photograph at the top of this post shows a small coil of rope lying on deck. You are looking down on it. The part leading in from the left is coming from the belay, and there is a figure-8 knot in the bitter end. Given those conditions, there are two things very wrong with this picture. The problem isn’t that the rope is hand-made, and thus a bit irregular, nor is it that gouty knot. If you think you know at least one answer, send it in to puzzle@briontoss.com. If you think you know both answers, send both; no penalty for incorrect answers, so feel free to speculate. Bonus points if you can find the ABK citations for the answers.”

Thanks to all of you who responded! Not everyone had the right answers, but a lot of you exhibited a courageous/intrigued/imaginative willingness to put forward ideas. Blessings on you.

And now to the answers. The first thing wrong with the picture is that the rope in the coil is left-laid, but the coil is made clockwise. Right-laid rope should be coiled clockwise, as it is less liable to hockle or tangle when it runs, because the twist of the rope will get looser, not tighter as the rope straightens. For the same reason, left-laid rope should be coiled counterclockwise. Left-laid rope is quite rare, and many people don’t even recognize it when they see it. Some entrants identified the rope in the picture as “hawser-laid,” and I had to disqualify that answer. While it is true that hawser-laid rope is conventionally left-laid, it is also made up of three or more whole smaller ropes.  But the rope in the picture is not made up of smaller ropes, but of yarns that have been twisted together to form strands. It’s just plain old rope.

The second thing wrong with the picture is that the bitter end is on top of the coil. This makes the coil much more likely to tangle when it runs. Always lay a coil on deck “face down,”  i.e. with the end on the bottom, to minimize the likelihood of tangling. Some entrants said that the end should be coming up through the middle of the coil, but this is only true for a multilayered factory coil, and even then it matters which end of the coil you pull from.

The winner of the one-correct-answer group is….. Joe Schmidbauer, who wrote, “This is S-laid rope and should be coiled in the opposite direction.” S-laid is the modern usage equivalent of left-laid, taken from the angle formed by the central portion of the letter S. In this usage, right-laid rope is Z-laid. For more on this and much else about rope, see https://en.wikipedia.org/wiki/Rope.

Joe — and lots of other people — noted that the bitter end lacked a whipping or other pleasing finish, but I don’t see this as structurally wrong, just crude. As Dustin Higdon put it in his entry, “I don’t know if it’s technically ‘wrong’ but it’s certainly poor form.”

Congratulations Joe. Be in touch to tell me which DVD you want.

The winner of the both-correct-answers group is…. Andrew Schmitz. Andrew’s entry was downright scholarly in its completeness, so I will just show the pertinent parts here:

1) The line shown is left hand lay, so the coil should be coiled counter clockwise, rather than clockwise as shown.

2) The coil should be flipped over on deck, such that the running end, from the belay, leads to the top of the coil.  If the line needs to run, the coil as shown will more likely foul than if the coil is flipped, so that the running end feeds off the top of the coil.

extra credit:  the rope is unlayed at the stopper knot in a very “lubberly” fashion.  It would be more ship shape to have a whipping on the end of the line.

as for citations:

on page 512 in the beginning of chapter 40 Ashley tells us “Right hand, or plain-laid, rope is properly coiled clockwise…”

ABK 3086 instructs us to lay a coil face down such that it runs clear

page 605 in the glossary: the definition of with the lay, or with the sun, in reference to coiling a right hand laid rope clockwise

To that I will add Ashley’s #3317: “On some smart naval craft the knots were at the forward hole of the deadeye on both sides of the ship, left-laid rigging being used on the port side. If cable-laid rigging were used, all the knots were on the right side of the deadeye.” How’s that for deeply obscure rope geek info?

Andy, let me know how you would like that book personalized.

Given the enthusiastic response this puzzle had, I intend to post some more. If you’d like to join the party, write to puzzle@briontoss.com with your ideas.

In the first installment we looked at the principles underlying the Ashley Book of Knots. This time we’ll take a look at some applications, as well as a sidebar on Ashley’s pioneering work on knot security. Both installments are from an essay I wrote for the book “Thou Shalt Knot,” produced by the New Bedford Whaling Museum to accompany their magnificent exhibit celebrating the life and work of Clifford Ashley.

And now on to Part 2.

Most of the material in the ABK would be familiar to 18th- and 19th-century riggers and sailors, but that doesn’t mean it is outdated; many 20th and 21st century traditional sailing vessels, including large square riggers, have benefited from this book, notably from the chapter on Practical Marlingspike Seamanship. Here there are scores of configurations that provide modern riggers with details on basic procedures, as well as solutions to more obscure applications. This chapter concentrates on integrating rope and hardware to create, control, and manipulate structures. Thus we see rope integrated with sails, blocks, hooks, deadeyes, gammons, yards, masts, anchors, etc., as well as rope and twine integrated with each other into practical configurations (service, seizing, hitching, whipping, etc.)

Want to know how to apply a “garland” for hoisting a top- mast? Ashley shows how, by the French as well as the English method (#’s 3416 & 3417). Need to seize a batten to a shroud? Choose from among #’s 3368-3372. Need to install some deadeyes? Take a deep breath and study # 3278 – 3318. There you will see representative examples from the beginning of the 17th century on, complete with commentary on configuration and installation, including an elegant emergency repair variation (#3302).

These items, along with the almost 400 others in this chapter, might seem to have no use in contemporary rigs, but many of them have direct application today, because rigs are now, after a century-plus of hiatus, once again being made with rope – high-modulus rope, out of fibers like Spectra and Vectran – but rope nonetheless, which is unsuited to the machined terminals used on wire, but which does reward the use of creative marlingspike skills. Practical Marlingspike Seamanship is a database of ocean-proven practices that today’s riggers are regularly digging into. As a final example, consider the Selvagee (#3147), which has nowadays been reincarnated for industrial use as the ubiquitous round sling, as well as shackle-replacing “loopies,” and even as standing rigging, made out of high-modulus fibers. 

Nor is this the only chapter being mined; Miscellaneous Holdfasts (chapter 26), Occasional Knots (chapter 27), and Lashings and Slings (chapter 28), could all have been rolled into a chapter called “Not Quite Ready for Practical Marlingspike Seamanship.” Here we have rope interacting with bottles, bags, bollards, bridles, blubber, and barrels, as well as hammers, flags, flag poles, tennis nets, sounding leads, thwarts, and much more.

To study these chapters is to see the possibilities of rigging. You might never need to secure a stuns’l tack block to the end of its boom (#1930), but the principle behind this entry – toggling – is nowadays integral to the design of many high-tech racing blocks. And while you might never need to pull a stump out by its roots (#2014), the principles behind this entry underlie all of rigging. This little drawing, and its accompanying text, is a highly-condensed treatise on vectors, leverage, compound leverage, elasticity, tension, compression, shear, and ingenuity (don’t have a set of lashed-together spars? Use an old door).

But then, it is hard to find a chapter that doesn’t have at least something of value to riggers. Even the Tricks and Puzzles chapter has tips on, among other things: the unreliability of the Clove Hitch; descending a cliff with a too-short rope; novel and sometimes useful methods for tying the Bowline and the Sheet Bend; restraining a prisoner; and escaping from restraints. The latter (#’s 2613 and 2614), are two of many topological exercises in this chapter. Of course, all knots are miracles of topology in action, but some fairly esoteric manipulations play a surprising role in many rigging applications, from the forming of knots like the Bowline on a Bight (#1080), to “dipping” multiple mooring line eyes for easy removal, to locking Brummel knots, much used in single-braided rope.

Speaking of braided rope, Ashley only mentions it briefly (#232), but you will find dozens of braids in his book, from 3 up to 61(!) strands. Flat braids, square braids, round, half-round, triangular and oval braids. Braids used for utility, or for decorative purposes only. A profusion of braids, published just before the development of industrial-scale machinery caused single- and double-braid ropes to explode onto the scene, transforming rigging utterly. Braided rope can be stronger per diameter than laid rope, as well as less elastic, more resistant to hockling. It fits better on winches, and can be “tuned” as it is braided to create ropes that cover an historically unprecedented range of desired characteristics. And it can be laid up from advanced materials that are many times stronger than steel per pound. And Ashley completely missed the boat on modern rope construction as well as modern rope materials.

If I had opened my copy of the ABK for the first time today, and seen that it said next-to-nothing about braided rope, I probably would have put it back on the shelf, and looked for something more pertinent to my trade. And it would have been my loss. I would have been like a physicist ignoring Newton, because he had nothing to say about quarks, or a director ignoring Orson Welles because he never used a green screen. Like those worthies, Ashley was a technician, but also, literally, an artist, who saw and described things in a way that no one else had before, and who made possible the advances that came after his time. If he had lived just a few years longer, he no doubt would have recorded/invented/speculated on the vast new field of possibilities that was opened with the revolution in braided rope: new knots, new splices, new configurations, new ways to handle new types and magnitudes of loads. But while it is true that we lost his direct input, his greatest contribution, even in his day, was not that his book was utterly encyclopedic, but that it provided a powerful way to approach knots. It can no longer lay claim to containing “Every practical knot,” as the subtitle on the cover still claims, but that hardly matters, because Ashley concentrated so fiercely on the rest of that subtitle, which reads, “What It Looks Like, Who Uses It, Where It Comes From, and How to Tie It.” If there had been room for a longer subtitle, the publisher might well have added, “What It Is Good For, Which Ones You Probably Want to Avoid, Which Ones Look Archaic or Silly But Might Just Surprise You With How Useful They Become Some Day, and Why You Should Be Studying All of This So That You, Too, Can Make Meaningful Contributions to This Ancient Body of Knowledge, Or At Least Help to Keep It Alive.”

Sidebar: Testing Knots

In the first chapter, after some extensive remarks on the history and idioms of knotting, Ashley describes a series of tests he conducted on knot security (#’s 63-68), a consideration that was quite novel in his day. The test was of bends, with each knot tied in extraordinarily slick, springy mohair. Rather than a steady pull, each of ten bends was subjected to “… a series of uniform jerks, applied at an even rate of speed, using the drip of a faucet for a metronome.”

The results showed that some knots, like the reef knot, have a deserved reputation for untrustworthiness, but also that others, like the sheet bend, were not the faultless icons that we had thought they were. In the 1940’s, mohair was such an anomalous material for riggers that these tests might have seemed pointless, but just a few years later, when the advent of slick, springy synthetic fibers brought knot security to the fore, we already had the beginnings of a database, thanks to Ashley. Elsewhere in the book, the notion of security is addressed in binding knots like the constrictor (#1249), loop knots like the double bowline (#1013), and hitches like the camel hitch (#1741), among many other examples. For today’s riggers, faced with ever-slicker materials and ever-higher loads, Ashley’s concern for security seems prescient. His approach, further developed long after he was gone, includes such vital knots as John Smith’s extra-secure Marlingspike Hitch, arborist’s friction hitches, a variety of extra-secure bowlines, and the wonderful Icicle Hitch (also from Smith). The latter was directly inspired by Ashley’s attempts to create hitches (#’s 1985 &1986) that would hold when pulled towards the narrow end of a smooth, tapering spar.
