In schooners, cutters and open boats, the length between perpendiculars for tonnage is taken from where the line of the lower edge of the rabbet of the keel is intersected forward by the squaring down of the fore side of the stem at the bed of the bowsprit, and measuring the length from this point to where the lower edge of the rabbet of the keel, if produced would cut the after side of the main post; the deduction fromt this length for the length for tonnage for rake of stem; the rake of post being considered as accounted for by the above measurement; the rest of the rule the same as for other ships. That the perpendiculars placed on the draught for a man-of-war may not be mistaken for the length between perpendiculars for tonnage, it is ordered that the former shall be taken from the aft part of the rabbet of the stem to the fore part of the rabbet of the post at the height of the upper deck.
