6. Rope Materials – Natural  Cotton – cheap, weak, not shock absorbent (clothsline). Woven or laid. NOT to be used nautically.  Sisal – inexpensive, weaker than manila. Must dry, will rot, laid.  Manila – best natural material. Expensive. Must dry, will rot, laid. Minimum stretch. ¼” = 600# test.

7. Rope Materials – Synthetic (1)  Polyethylene – floats, chafes, no rot, sunlight deteriorates rapidly, ¼” = 1200# test  Polypropylene – floats, no rot, sunlight deteriorates rapidly, slightly stronger, resists oil  Dacron (polyester) – minimum stretch (9%), better for sheets & halyards, no rot, oil resistant, usually woven, ¼” = 2400# test

8. Rope Materials – Synthetic (2)  Nylon – maximum stretch (20%), best for anchoring and towing. Oil, chemical, abrasion resistant. Sunlight resistance good. ¼” = 1800# test. Usually woven.  Samson Amsteel – Proprietary new material, 4% stretch, sunlight resistant, woven, ¼” = 8600# test = steel

9. Laid Rope  a. Slivers  b. Slivers of fiber twisted in one direction = yarn  c. Yarns (3) twisted in opposite direction = strand  d. Strands (3) twisted in opposite direction = rope  e. Rope twisted in opposite direction = hawser

10. Laid Rope Info  Normally three strands  Normally right-handed  Cable-laid – three ropes laid together  Hawser – any rope over 5” circumference  Can be four strands with heart

11. Braided Rope  Core surrounded by fully-sheathed braid protects core  Braided core  Stranded core  Core provides strength  Braid provides protection from  Abrasion  Sunlight

12. Rope Sizing  Normally sized in diameter up to 2”  3/16, ¼, 5/16, 3/8, 7/16, ½, etc.  Then sized in circumference (3.14 x dia)  Old times, all nautical rope was sized in circumference, but no more.  5” hawser is circumference, should be about 1.6” diameter!  7” rope is a bit over 2” in diameter

13. Rope Length  Rope in store – normally FEET or METERS  Could be in fathoms (6 feet)  Coil of rope usually:  100 fathoms (land)  200 fathoms (nautical)

14. ORD-6b b. Using both large and small lines, tie and explain the following knots: stevedore's knot, French (double) bowline, bowline on a bight, timber hitch, rolling hitch, marline hitch, and midshipman's (taut line) hitch.

16. Stevedore's Knot  Stopper knot  Make loop  Wrap 1½ times  End through loop  Pull tight

17. Stevedore Animated www.animatedknots.com/stevedore/#Movie

18. French (Double) Bowline  Start as a regular bowline (right)  Run line around the loop again (right)  Bring line up through hole as with regular bowline (middle)  Bring line around back, down through hole, as a regular bowline  Pull knot tight (left)

19. French Bowline Animation  Can't find

20. Bowline on a Bight  Make a bight (big, long loop in line)  Start it just like a bowline  Bring the end of the loop down and around the big loop (or feed big loop through)  Slide the loop end up and adjust all to fit need  Loops hold same size

21. Bowline on a Bight Animation http://www.animatedknots.com/bowlinebight/

22. Timber Hitch  Run a line around a timber, leaving 6”-1' left  Bring the bitter end around the standing end, and tuck it back on itself  Tuck a minimum of three times, tighten  You may want to put a half hitch around the towed end for a big or long timber

23. Timber Hitch Animation http://www.animatedknots.com/timber/

24. Rolling Hitch  Wrap one full time around  Wrap a second full time around  Cross over the two lines  Come under the crossover line  Tighten  Pull along the length of the pole (down)

25. Rolling Hitch Animated https://www.youtube.com/watch?v=OX_kU_jYecU

26. Marline Hitch  Start with a clove hitch around boom(s) and sail  Space out 1-2 feet, hold, and put a half hitch  Insure the half hitch goes in on top and out the bottom  Cover the whole sail (or other long skinny object)  Tie off with clove hitch or to something else

27. Midshipman's (Taut Line) Hitch  Pass line over the bar or line you are tying to  Bring it down, around, and in between your line and the bar.  Make a second loop in between  Continuing the same direction, cross over the two loops, wrap once  Slide under your wrap, tighten

29. ORD-6c Demonstrate the ability to secure a line to pilings, bitts, cleats and rings and to coil, flake and Flemish a line.

31. Bitts  Seldom seen in some parts of US  Eye splice / bowline OR wrap around far bitt  Cross to near bitt  Repeat several times on each bitt  Used on large vessels and shore installations

32. Piling  Piling – big tall post, often in water  Use a fixed knot – eye splice or bowline  Temporary – two half hitches or midshipman hitch  Don't use clove hitch or other knot that slips under constant movement

33. Rings  Lines are attached to rings semi-permanently by larks-head knots in an eye splice.  Use a bowline, or midshipman's hitch

34. Coil a Line  Right hand, even loops  Half twist as you coil  Save two loops to finish  Wrap around middle  Finish with bight through top

36. Flake a Line  Used to make a line run out without kinks  Take the kinks out of the line, beginning at where it pulls from  Start at the other end, lay figure 8s on the deck  Each 8 is on top, and slightly closer to the payout side

37. Flake a Line http://www.animatedknots.com/fig8flake/

38. Flemish a Line  Shake the line out so it is not twisted  Turn the bitter end in a small circle  Keep the line flat on the deck  Use two hands as the circle gets bigger  If needed, coil the line instead

40. ORD-8b Demonstrate how to cut and heat-seal a synthetic line, and whip the end of a plain-laid line using waxed cord or similar material.

41. Cut and Heat Seal  Synthetic line should be cut and heat sealed  “Guns” and “knives” do both at once – best  Can use knife and lighter  Keep end small to go through blocks

42. Common Whipping (1)  Lay a bight along rope  Start wrapping tightly from end of rope  When whipping length = rope diameter, slide cord end through bight  Pull bight under whipping about half way  Trim the ends

Common Whipping (2)  Make a large loop of twine  Lay one end 1” over the end of the line, the other end 2-3” down the rope  Start wrapping tight from the rope end  Wrap at least the diameter of the rope  Pull the twine at the end of the rope until it pulls the loop ½ way under the whipping  Trim the ends
