To twist r opes so that they will hold a nd not break is an a r t that comes natural to the sailor a n d the amateur will watch him in wonder as he does his work . Knots are j ust as important in these day s of steam vessels as they were in the days of the sailing vessel , and now when thousands of men are being trained to handle the fleets of ves s eI s buildi n g tyi n g knots is a part of their training . A t the Naval camps a n d the nautical schools the men are trained in squads a n d with a little practice they soon acquire the art . To aid those students this s book has been publi hed . It has been compiled from American and British Government records and from c o llec many other sources , so that it is as complete a s tion of knots as it is pos ible to obtain . s s m n e U . It will be of great a istance to of the . S “ U . S . U . S . n Navy , Naval Reserve , Ju ior Naval R e U . S . c S serve , the Nauti al chools and the U . S . Power S quadrons who are worki n g so loyally to $ aid their c in n ountry its time of eed . To these men this book is dedicated in the hope that it may be of some help to them in their work . H I STORY O F KNOTS a re Kn i n a n i , ots , accord g to ngenuous essayist “ $ probably as old as human fin gers a n d their history i lo s t in i i . s ant qu ty Doubtless w— hen man was first pla c ed on this earth he learned to make fastenings from the ten drils of climbing vi n es and trailing flowers whi c h twist themselves into odd fastenings as they lift themselves from the earth . The first cords were n S probably twisted g rasses a d rushes . ince those “ ' kn ts u s t r o we d early days q , like Topsy , have j g and ’ ma n s ingenuity has enabled him so to a rrange ropes n n r and cords that they will sustai weights , faste va ious articles t ogether a n d take up strai n s so that they will n hold u der ordinary conditions . S eamen are credited with havi n g devi s ed t h e most n n knots . They have i ve ted ties upon which dep end h ir ~ h i the safety of t e s p s and the lives of those on board . Operatives in many trades such as building have bor ~ rowed from the seamen their knots and applied them to n h a s their work . In some i stances the land operator invented new kn ots or ties to suit c onditio n s not fou n d on shipboard . To tie a kn ot properly or to be able to j oi n ropes s o that they will hold a n d withsta n d heavy strai n s is 10 so important with seamen that careful attention is paid to the instruction of the men in this particular work . At the many naval training camp s scattered about the country capabl e instructors show the r e c r uits how to properly make knots , ties , hitches , bends and splices , and until the recruit knows how to handle ropes quickly and properly he is not much use at sea . I oo o of n the nautical schools , t , and in the divisi ns the i i s t U . S . Power S quadron much attent on paid to his ’ part of the novice s instruction . The steamship is steadily driving th e sailing vessel f . O from the seas course on a sailing ship , where every spar is stayed by rope and where all the sails , n the propelling power , are ha dled by ropes , the ability to ~ p r o perly tie knots is more important than on a vessel driven by steam or oil engines , but on the powered vessel there are many occasions when it is necessary in to have a knowledge of knots , particularly handling o o carg es , in making fast t piers or moorings , in towing , in handling boats , and in hundreds of other instance s so that the steam engine is not making “ marlinespike $ seamanship a lost art . COR DAGE Rope is a word that is taken to mean almost every pliable material . Technically a rope is a cord one inch t . or more in diame er It is generally made of hemp , I n o i i . manila , coir, cott n, steel , ron or copper w re n k o i l studyi g the nature and uses of n ts , part cular y s those which come under the designation of splice , some knowledge of the mode and of the principles o n n which ropes are made , is esse tially necessary . The simplest and most effectual mode of obtaining the united strength of fibres composing the rope would be to lay them side by side and fa s ten th e m together o n at each end as in the selvagee , which is described 1 20 n n page . This pla , eve if the fibres of hemp n were of the necessary length , would be open to ma y obj ections ; hence it was necessary to devise some plan which would give unlimited length to the rope and at the same time preserve its torsion and portability . This has been achieved by the compressio n a n d twi s t o iff n i ing f the fibres in d erent directions , u t l they pro n duce a compact , hard and strong rope , neither breaki g the fibres on the one hand nor leaving them so loose as to be easily drawn out from the mass on th e other either extreme would be equally fatal in its results 1 2 and inj urious to the stability of the rope . This is _ achieved by the modern processes of rope making . First the fibres of hemp are loosely twisted to — n n gether , right ha ded , and form what is technically know o as yarn . Two or three yarns twisted t gether form a FIBRES TO CABLE strand ; three strands form a rope and three ropes a cable . The diagram illustrates this clearly . A i s a : yarn teased out to show the original fibre ;B shows the C yarn forming the strand ; the strands , H , and J form a nd G the rope D ; the ropes D , F , form the cable E . 1 3 A hawser rope is composed of three stran ds laid up left to right . - a - h a n d e d c o n s is ts A shroud laid rope , lso laid right , of four strands with a heart in the center .

  • A Very Short Guide to Knotting Terminology Used on These Pages
    KNOTS A very short guide to knotting terminology used on these pages. This is not an exhaustive list of knotting terms; it just contains some of the more unfamiliar words that we have used. If you wish to research the subject further, any good book on knots should have a knotting glossary. • Knot. Strictly speaking, a knot is tied in the end of a line as a stopper, such as the Thumb knot or Figure of eight knot. • Stopper knots are used to stop the end of a rope fraying, or to stop it running through a small hole or constriction. • Bend. A bend is used to tie two ropes together, as in the Sheet bend. Technically, even the Reef knot is a bend. • Hitch. A hitch is used to tie a rope to a spar, ring or post, such as the Clove hitch. Hitches can also be used to tie one rope onto another rope, as in the Rolling hitch. • Running End - the end of the rope that is being used to tie the knot. • Standing End - the static end of the rope. • Splice – A splice is used to fasten two ends of a rope together when a knot would be impracticable, as, for instance, when the rope must pass through a pulley. • Bight can have two meanings: -- The main part of the rope from the running end to the standing end -- Where the rope is bent back to form a loop. • Jam - when the knot tightens under tension and you cannot get it undone! Blackwall Hitch This is a simple half hitch over a hook.

  • BOAT CREW HANDBOOK – Boat Operations
    BOAT CREW HANDBOOK – Boat Operations Sumner I. Kimball, USLSS BCH16114.1 December 2017 Sumner Increase Kimball, USLSS A young lawyer from Maine, Sumner I. Kimball was appointed as the chief of the Treasury Department's Revenue Marine Division in 1871. He had joined the Treasury Department as a clerk 10 years earlier and had proven his abilities as a manager. Using his hard-earned political know-how, and a good dose of Yankee common sense, Kimball proceeded to completely overhaul the Revenue Marine and the hodge-podge system of lifesaving stations along the nation's coast that were also under the control of the Revenue Marine Division. His impact on both organizations would prove to be immeasurable. After the Civil War, the Revenue Marine, and the executive branch agencies generally, came under intense Congressional scrutiny. Economy was the name of the game during this time and expenditures were scrutinized across the board. Hence, Kimball decided to order the construction of new cutters not with iron hulls, which entailed considerable expense, but with proven wood hulls. The total number of petty officers and enlisted men was substantially cut and their pay reduced. Kimball also carried out a vigorous "housecleaning" of incompetent Revenue Marine officers and saw to it that discipline was tightened. A special object of his censure was the use of cutters as personal yachts by local Custom officials, a wide-spread abuse during that time. Kimball also put into effect a merit system to determine promotions. He also made one other great contribution to the quality of the Revenue Marine by establishing, in 1877, a School of Instruction, to train young officers.

  • Students Will Learn About Different Types of Knots and Their Uses in an Outdoor Setting. Students Will Practice Creating Each Knot and Master at Least One
    Knots Students will learn about different types of knots and their uses in an outdoor setting. Students will practice creating each knot and master at least one. Students will make a paracord bracelet. Materials Included in the Kit: Not Included in the Kit: • 7ft length of paracord • Scissors • Side button buckle • ADULT SUPERVISION - Lighter Lesson Knots are bumps in a rope. These bumps can be made in all different shapes and sizes BUT, they also can be used for a lot of different things! Can you think of activities that we do that we need knots? We use them almost every day putting on shoes for sure. Survivalists and naturalists also use knots when camping, boating, and fishing. Doctors use even use them in surgeries! Each type of knot has its own special job and today we are going to learn about four knots and practice them. Activity 1: tying four basic knots You can follow step by step through each knot following the instructions on the last pages of the lesson 1) Let us start with one of the most simple knots out there - an OVERHAND KNOT. It will look familiar to you, what do you use this one for…tying your shoes? 2) A SLIP KNOT forms an adjustable loop or noose at the end or middle of a rope. You can place the loop around a support and then tighten the knot by sliding it. This makes it simple attaching a line to a bar or post. 3) If you want to tie your fishing line securely to a hook, swivel or lure, the IMPROVED CLINCH KNOT would be your best bet.

  • Knot Masters Troop 90
    Knot Masters Troop 90 1. Every Scout and Scouter joining Knot Masters will be given a test by a Knot Master and will be assigned the appropriate starting rank and rope. Ropes shall be worn on the left side of scout belt secured with an appropriate Knot Master knot. 2. When a Scout or Scouter proves he is ready for advancement by tying all the knots of the next rank as witnessed by a Scout or Scouter of that rank or higher, he shall trade in his old rope for a rope of the color of the next rank. KNOTTER (White Rope) 1. Overhand Knot Perhaps the most basic knot, useful as an end knot, the beginning of many knots, multiple knots make grips along a lifeline. It can be difficult to untie when wet. 2. Loop Knot The loop knot is simply the overhand knot tied on a bight. It has many uses, including isolation of an unreliable portion of rope. 3. Square Knot The square or reef knot is the most common knot for joining two ropes. It is easily tied and untied, and is secure and reliable except when joining ropes of different sizes. 4. Two Half Hitches Two half hitches are often used to join a rope end to a post, spar or ring. 5. Clove Hitch The clove hitch is a simple, convenient and secure method of fastening ropes to an object. 6. Taut-Line Hitch Used by Scouts for adjustable tent guy lines, the taut line hitch can be employed to attach a second rope, reinforcing a failing one 7.

The DOUBLED hitch, tied by ,:,;,: taking a second exactly parallel turn with a longer end, is an IMPROVE- MENT and a good absorbant for a shock load such as a fall on the safety line. See description and Fig. 37. With or without a carabiner. the DOUBLED tie can also serve as a “STOPPER” in the end of a line that might escape-for instance, a low- ering line, al. ascending line, a rappel line, etc. It is even more efficient if a ring or washer is placed ahead of it. FRONT COVER ADJUSTABLE BOWLINE STIRRUP: This is the Standard Bowline tied with two ends leaving a bighted end for suitable hitch attachments such as the Prusik, Ring, Catspaw, etc. Length can be varied to suit the climber’s height, the loops adjusted singly or together, and when advis- able, the dangling ends may be square-knotted around the ankle to hold the foot well into the stirrup.
