The art of apparelling and fitting of any ship with masts, yards, and cordage. [electronic resource] : Wherein is shewed a true proportion for the masting, yarding, and apparelling of any ship, whose length, breadth, and depth is known: with rules for the sizes and lengths of all sorts of cordage that belongs to any ship. All which is performed by a scale called the mariners scale, or by two sliding lines of numbers. Whereby, if the length and thicknesse of the main-mast be accounted upon it, there may be found (only by inspection) the length and thickness of all the other masts and yards, and also the sizes, the lengths, and the totall number of fathams of every size cordage for the apparelling of any ship, without using of compasses or altering the scale.
