What is this "pin" thing called?
"Vince Brannigan" wrote in message
... [ SNIP ] Belaying pins actually function as a machine. The pin protudes through the pin rail. the "rope" comes down vertically past the pinrail and a "turn" is takn around the tail of the pin. This changes the angle of pull 90 degrees and allows more people to pull on the rope than if it just came down vertically. The rope can also be attached to a windlass. Friction between the rope and the pin rail adds to the work load, but in a trained crew is also used to grab the rope while you change hands or tie off the rope. the rope is tied off by taking a "hitch" in the rope in which the standing part is crossed over itself and dropped over the top of the pin. Pulling on the rope tightens down the "belay knot" (yes its a knot) on the head of the pin if the load is very heavy and you need more friction you can take a second belay by taking a second turn aroun the tail and making a "double belay". All you guys know a little bit too much, which is disgusting me. I will soon expound on either the exact details of how early 19th century cannons were secured (complete with the nomenclature of the ropes), or ruminate on careening, or perhaps speculate at length on the design of galley oar blades.
