Ropes (pgs 77-84) Flashcards
Uses of figure of eight knot
Can be tied on the end of a newly cut line to prevent fraying, or it can be used as a stopper knot
Uses of reef knot
Used for reefing sails. It’s suited for smaller ropes, and shouldn’t be used to tie two ropes together.
Uses of sheet bend and double sheet bend
Used for joining ropes of equal or different sizes, and the same or different materials. The larger rope should be used to make the eye.
Uses of the bowline
Used to create a loop at the end of a line.
Uses of clove hitch and round turn and two half hitches
Used for making line fast to a spar or post. Can slip sideways, or jam if the rope is wet. A round turn with two half hitches can be tied while the rope is under tension.
Laid or braided rope?
A braided rope typically has more stretch and less strength, is more pliable, does not kink, and its surface is easier to handle.
Features of nylon rope
Very smooth, high stretch does not float, absorbs some water, does not swell, moderate resistance to UV and chaffing, highest breaking strain. Best rope for anchor lines.
Features of polyester rope
Soft, least stretch, does not float, does not absorb water, does not swell, best resistance to UV etc., second highest breaking strain. Best rope for halyards, sheets, and mooring lines.
Features of polypropylene rope
Waxy, moderate stretch, floats, does not absorb water, does not swell, poor resistance to UV etc., second lowest breaking strain. This rope will do for halyards, sheets and mooring lines for small boats. It is recommended for towlines.
Features of polythene rope
Shiny, moderate stretch, floats, does not absorb water, does not swell, poor resistance to UV etc., lowest breaking strain. Recommended for towlines.
How should you care for your ropes?
Examine your ropes frequently for signs of wear or damage. Stow your ropes out of direct sunlight, and avoid using them near sand, grit or rust.
