Measurement of Tonnage. RULE II. For Ships Merchant Shipping (Part II. Registry.) as above directed; measure (also at the Middle of its Height) the inside Breadth of the Space at each of the Points of Division, also the Breadth of the Stem and the Breadth at the Stern; number them successively 1, 2, 3, &c., commencing at the Stem; multiply the Second and all the other even numbered Breadths by Four, and the Third and all the other odd numbered Breadths (except the First and Last) by Two; to the Sum of these Products add the First and Last Breadths; multiply the whole Sum by One Third of the common Interval between the Breadths, and the Result will give in Superficial Feet the mean horizontal Area of such Space; measure the mean Height of such Space, and multiply by it the mean horizontal Area, and the Product will be the Cubical Contents of the Space; divide this Product by One hundred, and the Quotient shall be deemed to be the Tonnage of such Space, and shall be added to the other Tonnage of the Ship ascertained as aforesaid; and if the Ship has more than Three Decks, the Tonnage of each Space between Decks above the Tonnage Deck shall be severally ascertained in manner above described, and shall be added to the Tonnage of the Ship ascertained as aforesaid. XXII. Ships which, requiring to be measured for any Purnot requiring pose other than Registry, have Cargo on board, and Ships which, Registry with requiring to be measured for the Purpose of Registry, cannot be measured by the Rule above given, shall be measured by the following Rule, herein-after called Rule II. : Cargo on board. Length. Breadth. Girting of the (1.) Measure the Length on the Upper Deck from the Outside of the outer Plank at the Stem to the Aftside of the Stern Post, deducting therefrom the Distance between the Aftside of the Stern Post and the Rabbet of the Stern Post at the Point where the Counter Plank crosses it; measure also the greatest Breadth of the Ship to the Outside of the outer Planking or. Wales, and then, having first marked on the Outside of the Ship on both Sides thereof the Height of the Upper Deck at the Ship's Sides, girt the Ship at the greatest Breadth in a Direction perpendicular to the Keel from the Height so marked on the Outside of the Ship on the one Side to the Height so marked on the other Side by passing a Chain under the Keel; to Half the Girth thus taken add Half the main Breadth; square the Sum; multiply the Result by the Length of the Ship taken as aforesaid; then multiply this Product by the Factor .0018 (Eighteen Ten-thousandths) in the Case of Ships built of Wood, and by .0021 (Twentyone Ten-thousandths) in the Case of Ships built of Iron, and Merchant Shipping (Part II. Registry.) and the Product shall be deemed the Register Tonnage Measurement of Tonnage. in Spaces on upper Deck. (2.) If there be a Break, a Poop, or other closed-in Space on Poop and the Upper Deck, the Tonnage of such Space shall be other closedascertained by multiplying together the mean Length, Breadth, and Depth of such Space, and dividing the Product by 100, and the Quotient so obtained shall be deemed to be the Tonnage of such Space, and shall, subject to the Deduction for a closed-in Space appropriated to the Crew as mentioned in Rule I., be added to the Tonnage of the Ship ascertained as aforesaid. RULE III. XXIII. In every Ship propelled by Steam or other Power Allowance requiring Engine Room, an Allowance shall be made for the for Engine Space occupied by the propelling Power, and the Amount so Room in allowed shall be deducted from the gross Tonnage of the Ship Steamers. ascertained as aforesaid, and the Remainder shall be deemed to be the Register Tonnage of such Ship; and such Deduction shall be estimated as follows: (that is to say,) (a.) As regards Ships propelled by Paddle Wheels in To be rateable which the Tonnage of the Space solely occupied by and in ordinary necessary for the proper working of the Boilers and Machi- Steamers. nery is above Twenty per Cent. and under Thirty per Cent. of the gross Tonnage of the Ship, such Deduction shall be Thirty-seven One-hundredths of such gross Tonnage; and in Ships propelled by Screws in which the Tonnage of such Space is above Thirteen per Cent. and under Twenty per Cent. of such gross Tonnage, such Deduction shall be Thirtytwo One-hundredths of such gross Tonnage: (b.) As regards all other Ships, the Deduction shall, if the May be meaCommissioners of Customs and the owner both agree there sured where to, be estimated in the same Manner; but either they or he the Space is unusually may in their or his Discretion require the Space to be mea- large or small. sured and the Deduction estimated accordingly; and whenever such measurement is so required the Deduction shall consist of the Tonnage of the Space actually occupied by or required to be inclosed for the proper Working of the Boilers and Machinery, with the Addition in the Case of Ships propelled by Paddle Wheels of One Half, and in the Case of Ships propelled by Screws of Three Fourths of the Tonnage of such Space, and the measurement and Use of such Space shall be governed by the following Rules; (that is to say,) (1.) Measure the mean Depth of the Space from its Crown to Mode of Meathe Ceiling at the Limber Strake, measure also Three, surement. or, if necessary, more than Three Breadths of the Space at Merchant Shipping (Part II. Registry.) at the Middle of its Depth, taking one of such Measurements at each End, and another at the Middle of the Length; take the Mean of such Breadths; measure also the mean Length of the Space between the foremost and aftermost Bulkheads or Limits of its Length, excluding such Parts, if any, as are not actually occupied by or required for the proper Working of the Machinery; multiply together these Three Dimensions of Length, Breadth, and Depth, and the Product will be the Cubical Contents of the Space below the Crown; then find the Cubical Contents of the Space or Spaces, if any, above the Crown aforesaid, which are framed in for the Machinery or for the Admission of Light and Air, by multiplying together the Length, Depth, and Breadth thereof; add such Contents to the Cubical Contents of the Space below the Crown; divide the Sum by 100; and the Result shall be deemed to be the Tonnage of the said Space: (2.) If in any Ship in which the Space aforesaid is to be measured the Engines and Boilers are fitted in separate Compartments, the Contents of each shall be measured severally in like Manner, according to the above Rules, and the Sum of their several Results shall be deemed to be the Tonnage of the said Space: (3.) In the Case of Screw Steamers in which the Space aforesaid is to be measured, the Contents of the Shaft Trunk shall be added to and deemed to form Part of such Space, and shall be ascertained by multiplying together the mean Length, Breadth, and Depth of the Trunk, and dividing the Product by 100: (4.) If in any Ship in which the Space aforesaid is to be measured any Alteration be made in the Length or Capacity of such Space, or if any Cabins be fitted in such Space, such Ship shall be deemed to be a Ship not registered until Remeasurement: (5.) If in any Ship in which the Space aforesaid is to be measured any Goods or Stores are stowed or carried in such Space, the Master and Owner shall each be liable to a Penalty not exceeding One hundred Pounds. XXIV. In ascertaining the Tonnage of open Ships the upper Edge of the upper Strake is to form the Boundary Line of Measurement, and the Depths shall be taken from an athwartship Line, extended from upper Edge to upper Edge of the said Strake at each Division of the Length.
