The masts and rigging also underwent important changes. At the beginning of the Eighty Years War (1590), an inhabitant of Enkhuizen, “Kryn Wouterez” by name, according to Brandt (_History of Enkhuizen_, Vol. I, p. 139), invented a process for making masts in several sections (~De Jonge~, Vol. I, p. 390). The masts, made first of two pieces, were, by means of this new invention, soon made in three parts each carrying a square sail. From this time, the old medieval rig of one large sail begins to disappear. In order to facilitate the evolutions of the ship, a square sail was placed on the bowsprit. Finally, the guns are placed more rationally and, imitating the practice on the Spanish caracks, some were located in the forward and after castles so as to command the deck. This arrangement recalls the practice of the Middle Ages, in accordance with which, in case of boarding, the crew retired into the castles whence a charge was made on the invaders. [Sidenote: II 143] [Sidenote: II 141] The vessel represented on the engraving of 1594, therefore, arose gradually from the old forms, but not without having felt the influence of the Mediterranean; this evolution leads us to the “Pinnace” of the XVIIth century. The ship was then richly ornamented and bedecked, and its sails, in accordance with use, carried handsome paintings. This custom disappeared insensibly during the century named, but the custom of decorating ships continued, none the less, for still a long time afterwards. According to ~Witsen~, fixed rules governed the construction of vessels from the XVIth century on. One strict rule, among others, did not allow the stem to project more than ⁷⁄₆, or less than ⅚ of its height, nor could the sternpost project more than a fifth or a fourth of its height. The author mentioned pretends that the stem was made with a marked slope, for the reason that it was believed that, under such conditions, the ships would glide more easily over the water (p. 47, column 2 at the end). At about one-third of the length of the keel from the stem, were placed from one to four main frames; the ship narrowed aft to such a degree that the wing transom was equal in length to half the greatest beam of the ship. The bow was full, which allowed the water to be thrown more easily aside. (~Witsen~, pp. 49 and 50.) The seams were calked and, in accordance with an old custom, covered with lead plates. The forward castle had been reduced in height while the after castle, on the contrary, had been raised. A fourth mast was placed in the stern to facilitate the manœuvring of the ship; this mast disappeared later on, when the bowsprit was adopted in the course of the XVIIth century.
