It is perfectly natural that Overijssel should have found itself under the influence of the other provinces. So, the “Hoy” is found along the Zuyder-Zee and, in the XVIIth century, the “IJzeren Verken” (anglice: iron hog) is a boat which should also be classed among the hoys and which ~Witsen~ calls a solid boat from Overijssel (p. 170). In the same way, the “statie” from Friesland is taken up in Overijssel, it being originally from the former province. [Sidenote: III 37] It will be useless to note that “Praamaken” and “Aaktjalken” are met with, that is to say a few boats having the shape of the “Praam” and of the Hoy, but without a stem. The bottom ends in the nose and the planking is assembled on this front face. Many “hoys” and “prams” have been built of iron during recent years. They still show characteristic differences among themselves, but it is to be expected that finally the forms will be confounded, when the “prams” will have taken fuller forms and the sheer of the hoys will have been reduced. THE KOFTJALK. [Sidenote: III 25] Finally, the “Koftjalk” must be mentioned again; it being a boat which is intermediate between the “Kof” and the “Hoy”. This kind of boat is originally from Groningen and resembles strongly the “Buitenmotten” of East Friesland. The “Koftjalk” is the precursor of the “Koffs” which later on replaced the “Cats and the Flutes”. [Sidenote: III 22] The “Koffs” therefore are not a spontaneous production, but were developed gradually as trade and industry extended or as navigable highways reached further and became improved. Thus the dimensions of the “Koffs” increased at the beginning of the XIXth century as the result of the creation of the Damsterdiep in 1791. If Hogendorp (Bijdrage tot de huishouding van den Staat, Vol. I, p. 183), still speaks, at the end of the XVIIIth century, of “Koffs” of 70 to 100 lasts, on the other hand, ~Le Comte~ (p. 16) mentions, at the beginning of the XIXth, “Koffs” of 100 to 150 “lasts”. The name of “Koftjalk” shows, on the other hand, that there is only a slight difference existing between the “Koff” and the “Hoy”. THE KRAAK. [Sidenote: III 47] [Sidenote: II 176] [Sidenote: II 178] The “Kraak” is a strongly built boat, with no sheer, with full and rounded bow and stern, belonging to the smack group. This vessel, of the size of a small “hoy”, belongs to the region limited by the broken line Amsterdam, Naarden, Nigtevecht, Haarlem, Zaandam and Amsterdam, this last city being considered as its place of origin. This very old type of boat is already to be seen in the engravings of the beginning of the XVIIth century, but there they are called “Lichter”. It is for this reason that ~Witsen~ speaks of the “Amsterdamsche binnenlichters”, as being “een plomb gebouwd zonder zeil of mast overdekt met hooge ronde luiken” (a heavily built boat, without masts or sails, covered by high round hatches). They were generally poled and had no masts; and carried a small deckhouse aft.
