Test #1 - Knots/Splices Flashcards
EYE SPLICE ON THIMBLE:
- Thimble prevents chafing of rope
- For use on an anchor (going from anchor line rope to chain or connecting to a shackle on an anchor chain)
BACK SPLICE & CROWN KNOT:
- Used to prevent the fraying of ends of lines
- Natural: 3 tucks; Synthetic: 4 tucks; Life: 5 tucks
EYE SPLICE:
- Creates a fixed loop
- Can be used for tying up to a post
- *Dipping the eye (when two or more loops around a post we ‘ dip the eye’ to remove our line without interfering with the other lines. Come up from the bottom and go over the other line(s))
SHORT SPLICE:
- Used for joining two ropes or making a strop
- *Criteria for grading: no tape, right amount of tucks, no bird caging, lines cut to a diameter
LINEMANS’ LOOP:
- Creates a fixed loop without having access to bitter ends
- Used for truckers hitch (a lashing method for cargo)
SHEET BEND:
- Used for joining two lines of unequal diameter
DOUBLE SHEET BEND:
- Used for joining two lines of unequal diameter in a more secure manner
- Used when there is a large difference in diameter
SURGEONS KNOT:
- Used for small lines (like twine)
- Has good holding power
- A symmetrical knot
REEF KNOT:
-Used for joining two lines of equal diameter
-Used for things that aren’t critical as knot is not very secure.
BOWLINE:
- Creates a fixed loop
- Relatively secure and versitile knot
- Can be used to join ropes, make fast or tie around an object
BOWLINE ON A BIGHT:
- Creates two fixed loops
- Can be used as a harness to suspend legs when in water
FIGURE OF EIGHT:
- Stopper knot
- Can be used for stopping pulleys
DOUBLE FIGURE OF EIGHT BEND:
- Used for joining two lines
- Can be used to achieve more length/extend a rope
- Approved for safety of life
DOUBLE FIGURE OF EIGHT BIGHT:
- Creates a “connection point”/fixed loop to attach another rope or piece of equipment
- Approved for safety of life
SHEEP SHANK:
- Non-destructive way to shorten a rope
- Can also be used to isolate a damaged piece of rope
- Access to bitter ends is not required
CAT’S PAW:
- Used for attaching to a hook
- *3 turns
HEAVING LINE KNOT:
- Adds weight to the end of a heaving line to make throwing easier
- Similar to a monkey’s fist but takes less time to tie/untie
ROUND TURN & TWO HALF HITCHES:
- Used to make fast to an object
- Relatively secure and easy to untie
- *2 half hitches = clove hitch
ANCHOR KNOT:
- Used for attaching a line to an anchor
- Slightly more secure than a round turn & two half hitches as the first half hitch is captive by round turn
CLOVE HITCH:
- Used to make fast to an object
- *2 ways: ‘turning’ (2 underhand loops) and ‘cast’ (appears as 2 parallel and 1 perpendicular line)
- Not used for critical things, not a relatively secure knot
CONSTRICTOR KNOT:
- Used to make fast to an object
- Slightly more secure than a clove hitch
PRUSSIK/SLIDING HITCH:
- Adjustable hitch can be loosened and tightened to slide up and down a rope
- Can tighten with either end
- Can be used for climbing (can hold weight)
HEAVING LINE BEND:
- Can be used for connecting a light messenger line to larger line (such as mooring line)
ZEPPLIN KNOT:
- Joining two lines of large diameter (greater than 1in)
- A symmetrical knot
ROLLING HITCH:
- Adjustable hitch can be loosened and tightened to slide up and down a rope
- Can only tighten with standing end
- Can be used for towing vessels. Often several vessels will be on a single towline, multiple positions need to be staggered and adjusted.
RUNNING BOWLINE:
- To create a loop that can slide and cinch
- Access to bitter end not required, good for use on long lines
