Tugboat Hitch
The Tugboat hitch (a.k.a. Backhanded mooring hitch or Lighterman's Hitch) is a knot ideal for heavy towing, or making fast to a post, bollard, or winch. It is easy to release, even under great Structural load, load. Tying To tie, take a single turn or a round turn around the post. Pass a Bight (knot), bight under the standing part, then drop the bight over the top of the post. Then make a bight in the rope on the other side of the standing part and drop it over the post. Note that in each placement of a bight over the post, the end's side of the bight should lead to the side away from the standing part—this will make casting off easier. Continue this repetition as necessary until secure (usually three bights). Finish by half-hitching a bight around the standing part or a round turn about the post. With heavy loads, it is important to have made enough bights and turns to reduce force on the final turns or a hitch—otherwise, it will be difficult to untie (a hitch) or may slip. ...

Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
