This is so evident that more ample explanations in regard to the nature of the “pram” have not been sought, and it is clear that the well known “Slijkpramen” of the province of Groningen are meant, the “Slijkpramen” being used just as well in the Dollard as in the peat bogs. They are small narrow boats, open above, with a straight longitudinal section, full bow and stern (like the hoys of Groningen). They are found also, with a few changes, under the name of “Vlotpramen”. When, after the completion of the Noord Willemsvaart in 1862, the direct connection between Overijssel and Groningen was accomplished and this latter province could be reached by the large Overijssel boats, which had also sides with no sheer, it was found evidently advantageous to call these vessels simply “Prams”. In this way, advantage was taken of the lower rate and, considering the resulting profits, good care was taken not to change the name “Pram” to that of “Schip”. It was only in 1903 that a judgment of the justice of the peace of Groningen decided that the vessels in question must be considered as “Schepen” and not as “Pramen”, considered by the above mentioned covenant. (Provinciale Groninger Courant, Dinsdag, 24 Februari 1903, Nᵒ 46.) This judgment, which put an end to the advantages mentioned above, was given as the result of a report of experts dated December 24, 1902. Among the preambles of this report is pointed out the French translation of an article of the tariff sheet appended to the convenant of 1817, where the word “Praam” was translated officially by “bateau dit vlotpraam”, meaning by that, and rightly, the small open “praam” of Groningen. The experts were mistaken, however, in saying that the present large “prams” were descended from the “vlotpraam” of Groningen. These prams are exactly like the Overijssel boats, but their dimensions are larger. Furthermore, they never belonged to the Groningen class of vessels. Their fine bow and stern are the most striking proof of this. In order to settle the type of the “prams”, search should not have been made alone in Groningen, as was done by the experts, but a comparison should have been made between the types of this province and those of Overijssel. To refer, as in the report of the experts, to a few earlier judgments where it is a question of “Praamschip” proves just as little, because there is no sense in considering the name of a boat, the type is what is required. The conclusion of the report is still more absurd, seeing that it says that the “praam” is a “boat” (schip), because the owner is called a “boatman” (schipper)! The covenant of 1817 was not applicable to the “Overijsselsche pramen” because these did not exist when the agreement was concluded. What precedes shows plainly that it is important to classify boats clearly and to determine beyond doubt the country to which the types belong.
