CHAIN-BOAT. A large boat fitted with a davit over its stem, and two windlasses, one forward, and the other aft, in the inside. CATFALL. The rope that forms the tackle for heaving up the anchor from the waters’ edge to the bow. It reeves through the sheaves at the outer end of the cat-head, and through the sheaves of the cat-block alternately. BOLSTERS. Sailing boat rope filled with rope-yarn, or shakings, which are placed under the shrouds and stays, to prevent their chafing against the trestle-trees. A Practical Rule for determining the relative Strength of Chain and Rope.Consider the proportionate strength of chain and rope to be ten to one-using the diameter of the chain and the circumference of the rope. Experiment has shown that by applying a constant, or even frequent, strain equal to half its strength, the rope will eventually break.

The size of Ropeis denoted by its circumference, and the length is measured by the fathom. The cordage allowed in the equipment of a man-of-war ranges from 1 1/4 (15-thread) to 10 inches inclusive. The hemp of commerce is put up in bundles of about 200 lbs.

Tons of Rope

In the days of sail the square rigged ship was by far the greatest consumer of rope. It had always been essential aboard ship, but the fully rigged ship with as many as 25 sails used literally miles of rope. Standing rigging, running rigging, bolt rope sewn into the edges of all the sails, foot ropes, braces, halyards and anchor cables were a few of the longer uses. The complete gang of standing and running rigging alone for one 400-ton brig launched at Portland, Maine, in 1865 was 3.8 miles long.

The best place to buy ropes and rigging for your sailing boat. Ropes and steel wire ropes for industry and architecture.

As the whole of the rigging is divided into standing and running, so a rope forming part of the rigging is divided into the standing part and the fall. The standing part is that which is made fast to the mast, deck or block. The fall is the loose end or part on which the crew haul. Standing in sea language means fixed thus the standing part of a hook is that which is attached to block, thain or anything which is to heave the hook up, with a weight hanging to it; the part opposite the point. Tackle is the combination of ropes and blocks; the combination of cables and anchors constitutes the ground tackle.

Unlike elastic stretch, viscoelastic stretch will only recover slowly over time once the load is released. In other words, the clutch catches the cover but the core can slide through until equilibrium is reached. The ‘entry-level’ coat is polyester of similar specification to the standard braid-on-braid most of us use.
