The up and down lines on the sail show where it is divided and where the mast comes. To heave to, the slew (after cringle) of the fore part of the log would be hauled up to the mat or to windward of it, easing the mainsheet as required. The split lug is not in much favour. The standing lug (or even balance lug) and foresail rig has all the advantages of the split lug without so much yard forward of the mast and without the disadvantage of not being able to lower the fore part or foresail. The most that can be said in favour of the split lug is that it points out the advantages of a main and foresail in preference to one sail.

In hoisting the topsail the lacing is passed through an eyelet hole in the luff of the sail and through a hoop, and so on. When the sail is hoisted chock-a-block the lacing is hauled taut; in lowering the lacing is slackened. Hoops facilitate the hoisting and lowering of the sail, and permit its being lowered and hoisted without a man going aloft

weather gauge - The condition of a vessel that is to windward of another one. In slang, to possess an advantage.
weather helm - The helm or tiller hauled to windward when a vessel owing to too much after sail has an inclination to fly up in the wind. If the centre of effort of the sails is much abaft the centre of lateral resistance, a vessel will require weather helm to keep her out of the wind. The tendency to fly up in the wind can he remedied by reducing the after sail, or setting more head sail, or by easing the main sheet. However, it is suggested that all vessels should carry a little weather helm.
