sail covers or coats - Protective covers for sails when furled.

"Sail Her Along" - In close-hauled sailing, an order given to the helmsman when he is keeping the vessel too close to wind, meaning that he is to keep her a little off ; sail her fuller or harder or "give her the whole weight of it," meaning the wind, and keep her passing through the water as fast as possible.

"Sail Her" - A general admonition to a helmsman to be very careful in his steering.

score - A groove to receive a rope or strop,

scowing an anchor - When small boats have to anchor on ground known or suspected to befoul, it will always be prudent to scow the anchor. Unbend the cable from the ring, and make the end fast round the crown, shank, and flukes with a clove hitch, and bring the end a back and stop it round the cable with spun yarn or hitches; take the cable back to the shackle and stop it. When the cable is hauled upon by the fluke of the anchor can be readily lifted out of its bed. Sometimes, instead of scowing the anchor a trip line is bent to the crown and buoyed.

sextant - A navigational instrument, used for measuring angles, as in celestial navigation when the altitudes of heaven bodies are taken when the known heights of objects ashore can be used to determine distance.

shackle - A metal link fitting typically U-shaped, with a pin across the throat, used to connect lines to an anchor or sail.

shear pin - A safety device, used to fasten a propeller to its shaft. It is designed to break when the prop hits a solid object, thereby preventing additional damage.

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.
