What is the purpose of the rope lock?
by
A rope lock is a lever-actuated device designed to secure the hand line and keep a balanced counterweight line set from moving up or down. A majority of counterweight rigging equipment requires this device.
And here’s how to use the butterfly knot to create a super tight rope line.
Loop the free end through an anchor point.
Loop the free end through the butterfly knot twice.
Pull on the free end (note the tension locks)
Tie the free end to the anchor point.
What is boating rope called?
The ropes that are used when sailing are all called ‘sheets‘ and each of these ‘sheets’ has their own name depending on which sail they are controlling, so when you trim the mainsail you use the ‘mainsheet’, when trimming the jib, you will adjust the ‘jibsheet’.
Nylon rope is the best for docking and mooring because of its strength and stretch. A double braid or three-strand line should do the trick. Easy to splice and reasonably priced, nylon rope is the way to go.

How many ropes should I have on my boat?
For spring lines, they should be equal to your boats length. Ideally, you should have two stern lines, two bow lines, and two spring lines on board. At a minimum, you should have one bow line, one stern line, and two spring lines.
What do you attach a rope to on a boat?
What material is marine rope?
Most marine ropes are now made from synthetic fibres such as nylon, polyester, polypropylene or Dyneema (or equivalent UHMWPE) instead of the traditional hemp rope or heavier chain constructions. Polyester is very popular as it has a low price point, great strength even when wet, and high abrasion resistance.
What kind of rope does a tugboat use?
Dynamica Mooring ropes are the preferred choice for all types of vessels; biggest containers, bulk carriers, navy, tankers, LNG vessels, ferries, barges, tug boats, fishing vessels to luxury yachts and smaller boats.
What kind of rope will absorb water?
The worst rope for marine use is cotton. As cotton is a natural fiber, it absorbs water and moisture easily.
What type of rope will float in water?
Polypropylene and polyethylene can. Floating ropes are made with either of polyethene or polypropylene fibres because of their floating properties and low weight.
Only ropes made from natural fibres (cotton, manila, coir, sisal etc) will shrink when wet. Why? When natural fibres come into contact with water (rain, dew, immersion, humidity etc) the fibres absorb water causing them to swell. The expansion of the width of the fibre causes the length to shrink.
What size rope do I need for my boat?
What size rope do you need? A good rule of thumb is 1/8″ of rope diameter for every 9 feet of boat length. In other words, if you have a 26-foot boat, you need 3/8″ line, but you should buy 1/2″ rope for a 28-footer.
What type of rope does not stretch when wet?
In fact, Dacron Polyester is one of the strongest rope materials you can use for mooring, fishing, boating, and tow lines. It is non-absorbent, mildew-resistant, hypoallergenic, will not stretch when wet, or let you down when you need it to perform.
How do I keep my rope tight?
Which is stronger twisted or braided rope?
Braided rope is stronger and is nicer on the hands than twisted rope, but it’s a pain to splice yourself. This means if you’re using a windlass and chain, and you are doing your own splicing, you’ll probably need to use twisted rope.
How can I make my rope stiff permanently?
One of the simplest ways to stiffen craft material is to use corn starch. Mixing water and corn starch creates a thick mixture that soaks into cloth and other materials such as rope. Once the starch dries, it makes the material stiff.
Essentially every knot that you tie in a rope will make the rope weaker than it is by itself. This is because knots cause tight bends in the rope whose outer circumference is greater than the inner part.
How do I stop my rope from untwisting?
One of the easier solutions and one that suits natural and man-made fibres, tape is a fantastic way to stop rope from fraying. Use duct tape or electrical tape to carefully cover the ends. You may need several pieces that overlap each other to keep the loose ends from escaping.
What makes a rope stronger?
In the simplest sense, fiber that is twisted or braided is stronger than the same bundle of fibers that are straight because the cord has more capacity to stretch. It won’t stretch to the same length as the straight fibers, but in exchange the fibers (and the spaces between them) can compress.
Does doubling a rope double its strength?
The doubled line is, of course, nominally double the strength. But the strength is reduced by the tight radius at the rings, and also by the knot.
