In the specifications and contra6ls for building in 

 modern shipbuilding are included inter alia :—^ 



Displacement Curve. 



Curve of metacentric height. 



Curve of statical stability. 



Tons per inch curve. 



The above designation or particulars being found, a 

 ship may be employed in a useful manner, and with a 

 proper application of stowage, the impair or waste 

 of the strength of the ship may be lessened, and the 

 quantity of cargo that may be carried on deck without 

 hazard to the ship may be ascertained. 



Certain methods for estimating approximately the 

 measurement cargoes of vessels and dead weight cargoes, 

 were suggested by the late Mr. MOORSOM, to whom is 

 attributed the system of measurement in the Merchant 

 Shipping A6t of 1854, now repealed by the M. S. A61 

 of 1894. 



With regard to the reckoning of measurement cargo, 

 the rule was to ascertain approximately for an average 

 length of voyage the measurement cargo at 40 feet to 

 the ton which a ship can carry, multiplying the number of 

 register tons contained unde^r the tonnage deck by the 

 fa6lor i|. 



In respe£l of dead weight cargo, multiply the number 

 of register tons under tonnage deck by the fa6lor i^, 

 and the product will be the approximate dead weight 

 cargo required. 



For coasting vessels, Mr. MoORSOM allowed an ad- 

 dition of 10 per cent to the foregoing results. 



In the sele6lion of the fa6lors shown, provisions and 

 stores were allowed.
