What is "laid rope?" |
Usually 3 strands of rope twisted together in a clockwise direction (called hawser laid). More expensive four strand rope is called shroud laid. |
|
|
What is Braided rope? |
A woven cover is used to protect low-stretch cores from abrasion and UV radiation--rope is flexible and easy to handle. Polyester is used for economy, but kevlar yarns are also available. |
|
|
What is plaited rope? |
Eight strands of which four are plaited clockwise and four counter--the result is a strong, flexible rope that avoids kinking |
|
|
What are the advantages of polyester rope? |
It is very popular for mooring lines as it is relatively strong with moderate stretch and good abrasion resistance--also, moderately priced. When braided, more suitable material for sheets; when pre-stretched, can be used for rope halyards, though intermittent tightening will be needed. |
|
|
What is nylon rope good for? |
This is ideal for anchor warps as it is strong, stretches up to 15% and absorbs shock. It is fairly resistant to abrasion, but has poor resistance to UV light. It is frequently used for dock lines, but if boat is left unattended for a long time, the rope will stretch and the boat will surge backwards and forwards too much. |
|
|
What is polypropylene rope good for? |
It's buoyant and light--does not absorb water. It stretches like polyester, but has poor UV resistance. It is used for rescue equipment such as danbuoys, lifebelts and heaving lines because it floats |
|
|
What is a bowline knot? |
Most important knot--used to put a temporary non-slip loop at the end of a rope. It may be used to secure the boat to a cleat or post ashore; to fasten sheets to a foresail; or to go around a casualty's waist in a rescue. Make a figure 6 with the left hand, bring the rabbit through the hole, round the tree, and back through the hole. |
|
|
What is a clove hitch? |
Useful for attaching fenders to the guardrail because it is easy to slide the fender sideways to reposition it and the height above the water can be adjusted quickly. It requires an extra half-hitch for security if the boat is to be left for any length of time. Around a rail once, end of rope lays over first loop, second loop under and through... |
|
|
What is a "Round turn two half-hitches?" |
A secure knot, easy to tie, easy to undue under load--secures a line to the base of a cleat or to a ring--some skippers prefer to secure to fenders to a rail because it doesn't shake loose like the clove hitch. Over bar twice, around the tree twice, then through the middle. |
|
|
What is a figure 8 knot? |
A quick and easy knot to tie, the figure of eight stops the end of a rope running out through a block. It is known as a stopper knot for that reason. Simply make a figure eight and pull. |
|
|
Reef Knot |
The reef knot, as its name suggests, is used for reefing. Reefing reduces the mainsail in windy weather and the unwanted sail is rolled and tied to the boom with a short length of the line. At the end of a loop, place the extension rope underneath, then curl the two ends to the inside of the loop, then pull! |
|
|
What is a sheet bend? |
The sheet bend is used for joining two ropes of different diameters. It is often used to lengthen lines to the shore when a number of yachts are alongside one another on a harbour wall. It is said that the two ends of the rope should finish up on the same side of the bend to prevent the knot from collapsing. |
|
|
What is a rolling hitch? |
The rolling hitch is similar to a clove hitch but has an extra turn before it is finished off. This extra turn locks the rope in place on a spar, which allows the knot to slide down to the right,but locks if an attempt is made to pull the rope to the left. Over once, cross the rope to the right once, then again, but put the end of the rope underneath the second bend and pull. |
|
|
What is important about coiling the rope? |
Lines stowed away in the cockpit locker should be coiled so they are ready for immediate use. If the rope is laid then it will almost certainly need to be coiled in a clockwise position (braided can be coiled any way.) Once the coils are complete, wind the rope around the coil around 4 times, working up towards your hand, then push a loop through the coil, and pull it down over the top. |
|
|
What is a Mediterranean Moor? |
In the Mediterranean and the Caribbean there is little rise and fall of water, so boats frequently moor stern to a quay (stone or metal outcrop for docking) so that everyone has easy access to the shore and more boats can be fitted in. |
|
|
Is laid rope used for: a.) sheets? b.) anchor lines? c. mooring lines? |
Mooring lines |
|
|
What type of rope is likely to be used for a heaving line? |
Polypropylene |
|
|
What is a back spring? What does it do? |
A mooring line that prevents the boat from moving astern. |
|
|
Would you place a rope on a winch in a clockwise or anticlockwise direction? |
Clockwise |
|
|
How would you limit chafe on a rope? |
Make sure that the lead is a fairlead (fitting on the deck edge to reduce chafe on a mooring line). Use plastic tubing at chafe points or wrap the rope in a material. |
|
|
Why are the stern lines crossed over when mooring stern-to a harbor wall? |
Sideways movement is minimized so that the transom (flat surface forming the stern of a boat or the horizontal beam reinforcing the stern) beam remains at right angles to the quay. |
