Directions for Knots: Reef, Bowline, and the Figure Eight
Directions for Knots: Reef, Bowline, and the Figure Eight Materials Two ropes, each with a blue end and a red end (try masking tape around the ends and coloring them with markers, or using red and blue electrical tape around the ends.) Reef Knot (square knot) 1. Hold the red end of the rope in your left hand and the blue end in your right. 2. Cross the red end over the blue end to create a loop. 3. Pass the red end under the blue end and up through the loop. 4. Pull, but not too tight (leave a small loop at the base of your knot). 5. Hold the red end in your right hand and the blue end in your left. 6. Cross the red end over and under the blue end and up through the loop (here, you are repeating steps 2 and 3) 7. Pull Tight! Bowline The bowline knot (pronounced “bow-lin”) is a loop knot, which means that it is tied around an object or tied when a temporary loop is needed. On USS Constitution, sailors used bowlines to haul heavy loads onto the ship. 1. Hold the blue end of the rope in your left hand and the red end in your right. 2. Cross the red end over the blue end to make a loop. 3. Tuck the red end up and through the loop (pull, but not too tight!). 4. Keep the blue end of the rope in your left hand and the red in your right. 5. Pass the red end behind and around the blue end. -
Bowline Tests
Boutique Bowlines International Technical Rescue Symposium Albuquerque, NM 2019 Kelly M Byrne Rescue 2 Training [email protected] The purpose of this paper is to document the research conducted in looking at various bowlines and their breaking strengths, as well as their susceptibility to cycling loading This was done in order to have a reference as to whether a bowline is suitable for an end line rescue knot as well as an anchor. Having initially learned the bowline as a great knot as a Cub Scout, told of the tremendous dangers of using it in any rope carried by the fire department, and finally heard it praises sung as I got further into rope rescue; I was understandably confused as to what the correct answer was. This was especially true when it comes to bowlines that weren’t your straight ahead “rabbit comes out of the hole” bowline. Boutique Bowlines, if you will. There was no data that I was able to find to suggest that these Boutique Bowlines were suitable for rescue work. Just a collection of anecdotal evidence. Defining a Bowline According to some members of the International Guild of Knot Tyers there are over 120 (!!) different names for bowline knots currently known; with at least 55 distinct variations of the bowline knot as well as several bowline based bends. Most of us are probably familiar with the “standard bowline”, what Ashley’s Book of Knots, where each knot is assigned its own unique number, has listed as #1010. While it is indeed a bowline, it is not the bowline. -

Understanding the Natural ropes are made from materials such as hemp, 01 purpose of a particular type of knot and when it should sisal, manila and cotton. They are relatively cheap but be used is equally important. Using the wrong knot in an have a low breaking strain. They may also have other activity or situation can be dangerous. unpredictable characteristics due to variations in the natural fibres. Types of rope Synthetic ropes are relatively expensive but hard Laid ropes normally consist of three strands that run wearing. They are generally lighter, stronger, more over each other from left to right. Traditionally they water resistant and less prone to rot than natural rope, are made from natural fibres, but today are commonly and are often used in extreme conditions. made from synthetic materials. Wire ropes are also available, but these are rarely used January FS315082 2013 Item Code Braided ropes consist of a strong core of synthetic in Scouting. fibres, covered by a plaited or braided sheath. They are always made from synthetic materials.

The Great Knot Competition
Outdoor Education 9 The Great Knot Competition Date of competition: ________________________ Learn to accurately and quickly tie useful knots from memory! The student with the most winning times on the knots will win the competition, with a second runner up. Incorrectly tied knots or memory aids will disqualify quickest times. 1st Place - First choice of chocolate bar 2nd Place - Chocolate bar Knots to be Timed: 1. Square Knot (Reef Knot) The square knot can join 2 ropes of the same size. It is the first knot we learn to make with our shoelaces. It looks like a bow and is hugely unreliable. Its breaking strength is only 45% of the line strength. The simple and ancient binding knot is also known by the names Hercules, Herakles, flat, and reef knots. It helps to secure a line or rope around an object. It creates unique designs of jewelry. 2. Figure 8 Follow Through Based on the figure 8 knot, figure 8 follow through knot is one of the ways of tying a figure 8 loop the other one being the figure 8 on a bight. It secures the climbing rope to a harness thereby protecting the climber from an accidental fall. 3. Bowline The bowline (pronunciation “boh-lin”) is a knot that can itself be tied at the middle of a rope making a fixed, secure loop at the end of the line. It retains about 60% of the line strength and has a knot efficiency of 77%. 4. Barrel Knot It is a friction knot (or slip knot) meaning that it will self-tighten around the object it is tied to when loaded. -

Fiction Group 4 -1
Fool in the Mountains Canadian International School, Ng, Emily - 15 He was late. Chen Jun Lang, top freelance travel journalist dubbed the next Bob Woodward, was late. How was he supposed to know he had to reply to a dozen more messages from his boss? Downing the cold coffee with one hand and struggling on his windbreaker over his neon yellow T-shirt with the other, his feet found their way into his hiking boots. He proceeded to strap his fanny pack and slung his trusty backpack over his shoulders, locking his hotel room door behind him. He blew down the staircase to the first floor and made a beeline for the exit and threw open the door, pasting on a half apologetic, half sheepish grin— Wind gusted past him, stirring fallen leaves across the plain concrete ground. The entrance was empty. Junlang furrowed his eyebrows. His private tour guide for today’s trip to Huangshan, or Yellow Mountain, was nowhere to be seen. Whipping his phone from his fanny pack, he dialed Mr Fan. The guide picked up after seven rings. “Hello sir?” “Hi Mr Fan! Where are you right now? I can’t see you at the hotel entrance and it’s nine fifteen already. You know, if you’re not coming, I will have to ask for a refund. I’m sure you wouldn’t want that to happen, would you?” “Mr Chen —” “I prefer Woodward.” “Yes, sir. Mr Woodward, I am sincerely sorry. I cannot be your guide to Huangshan. I have a family emergency to attend to.” Junlang’s eyebrows shot up in surprise. -
