As the length of the Masts are proportioned by the breadth of the Beame, so contrary wise, the length of the yard is proportio∣ned by the length of the Keele: The proportion of this, is not absolute: for he who will have a Taunt-Mast may have the Narrower-yards (and so contrary) but the best, and most absolute agreed on, is this, the Main-yard of the Ship is to be ⅚ parts of the length of the Keele: The top-saile yard is to be 3/7 of the Maine-yard: and the Maine-yard for bignesse, is to be ¾ of an Inch for a yard in length: the length of the fore-yard is to be ⅘ of the main-yard: The Crosse-Jack-yard, and sprit-saile-yard, is to be all of a length, but allow the Missen-yards, and sprit-saile-yards ½ an Inch thicknesse to a yard in length: Top the yards, (that is, make them hang even:) the Clew-lines doe properly top the Maine and fore-yards: but when the Top-sailes are Stowed, then the Top-saile sheates will top them: Brase the yard (that is, Travers aft that yard-arme, whose brase is haled) and by the brases we square the yards, that is, make them hang right-a-crosse, and one yard arme not Traversed more then the other: If the Shrowdes be set too forward, they will hinder the traversing of the yard: Traversing the yard, is to brase aft the yard.

When the Ship is not steered steddy, but she goes in and out with her head, they say she Yawes, this doth much hinder a ships∣way; and therefore when a man of warre is in Chase, he doth put such to the Helme, who can keepe her steddiest and evennest upon a point; which is done onely by Care and Judgement; to meet her with the Helme, before her head fall-off, or else come to.
