The Seaman's Friend. Richard Henry Dana
the main rigging, up through blocks at the mainmast-head, or at the after part of the top, up through the yard blocks, and are seized to the cap.
The fore and main topgallant braces are rove up through blocks under the topmast cross-trees, in through span-blocks on the topmast stays, just below their collars, up through the blocks on the yards, and the main are usually seized to the head of the mizzen topgallant mast, and the fore to the topmast stay, by the span-block. The mizzen topgallant braces generally go single, through a block at the after part of the main top-mast cross-trees. The royal braces go single: the fore, through a block at the main topgallant mast-head; the main, through one at the mizzen topgallant mast-head; and the mizzen, through a block at the after part of the main topmast cross-trees.
Halyards.—The lower yards are now hung by patent iron trusses, which allow the yard to be moved in any direction; topped up or braced. The topsail yards have chain tyes, which are hooked to the slings of the yard, and rove through the sheave-hole at the mast-head. The other end of the tye hooks to a block. Through this block a chain runner leads, with its standing part hooked to an eye-bolt in the trestle-tree, and with the upper halyard-block hooked to its other end. The halyards should be a luff purchase, the fly-block being the double block, and the single block being hooked in the channels. Sometimes they are a gun-tackle purchase, with two large single blocks. The lower block of the mizzen topsail halyards is usually in the mizzen-top, the fall coming down on deck.
The fore and mizzen topsail halyards come down to port, and the main to the starboard. The topgallant halyards come down on opposite sides from the topsail halyards; though the fore and main usually come down by the side of the masts. The fore and main topgallant halyards sometimes hoist with a gun-tackle purchase, but the mizzen and all the royal halyards are single.
The throat and peak halyards of the spanker are fitted in the following manner. The outer peak halyard block is put on the gaff, one third of its length from the outer end, or a very little, if any, within the leech of the sail; and the inner one, two thirds in. The blocks are fitted round the gaff with grommet straps, and are kept in their places by cleats. The double block of the peak halyards is strapped to the bolt in the after part of the mizzen cap, and the halyards are rove up through this, in through the blocks on the gaff, the inner one first, the standing part made fast to the double block, and the fall coming on deck. The upper block of the throat halyards is secured under the cap, and the lower block is hooked to an eye-bolt on the jaws of the gaff. This is a two-fold tackle.
The Spanker Brails.—The peak brails reeve through single blocks on the gaff, two on each side, generally span-blocks, and then through the throat brail blocks, as leaders, to the deck. The throat brails reeve through two triple blocks strapped to eye-bolts under the jaws of the gaff, one on each side, through the two other sheaves of which the peak brails lead. Each brail is a single rope, middled at the leech of the sail.
Tacks, Sheets, Clewlines, &c.—It is much more convenient to have the tack and sheet blocks of the courses fastened to the clews of the courses by hooks. Then they can be unhooked when the sail is furled, and, in light weather, a single rope with a hook, called a lazy sheet, can be used, instead of the heavy tacks and sheets with their blocks. This is also much more convenient in clewing up. The main tack is rove aft through the block in the waterways, forward through the block on the sail, and the standing part hooks to the block on deck. The fore tack goes through a block on the bumpkin. The sheets of the courses have the after block hooked to an eye-bolt in the side, abaft the channels, and the forward one hooked to the clew of the sail, the running part reeving through a sheave-hole in the rail. The sheets of all the square sails but the courses run from the clew of the sail, through sheave-holes in the yard-arms, through the quarter blocks, down on deck. The topsail sheets are chain, are clasped to the clews of the sail, and are fitted with a gun-tackle purchase at the foot of the mast. The topgallant and royal sheets are single. The topsail and topgallant clewlines reeve through the quarter-blocks. The royal clewlines are single, and the topsail and topgallant are a gun-tackle purchase.
