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. The _reef-tackles_ of the topsails reeve _up_ through blocks on the lower rigging, or futtock shrouds, _down_ through the block on the yard, down the leech of the sail and through the block on the leech, and are made fast to the yard on their own parts, with a clinch, outside of everything.
