We were provided with three thousand fathoms of tapered steel wire (varying from one and three-quarters to one and a half inches in circumference and weighing roughly a ton to the thousand fathoms in air); this was kept on a large iron reel (A) mounted on standards and controlled by a friction-brake. This reel was situated on the starboard side of the main deck, the wire being wound on to it by means of a chain-drive from the forward cargo-winch. For heaving in, our steam-windlass was fitted with a specially constructed drum (B), which absorbed the crushing strain and then allowed the slack wire to be wound on the reel (A), which was driven as nearly as possible at the same speed; the windlass usually heaving at the rate of four hundred and fifty fathoms per hour. A wooden derrick (D), provided with topping lift and guys, was mounted on the foremast by means of a band and goose-neck. At the outer end of the derrick, the dynamometer and a fourteen-inch block were attached. The maximum strain which could be supported was ten tons. In paying out, the wire was led from the head of the derrick to a snatch-block on the quarter (E), constructed so as to admit of its disengagement from the wire when it was necessary to heave in. This block kept the wire clear of the propeller and allowed us to have the vessel moving slow or fast as required, while the trawl was being paid out. The positions of the various parts of the trawling gear are shown in the plan on the opposite page. [TEXT ILLUSTRATION] Plan illustrating the arrangements for deep-sea trawling on board the 'Aurora'.
