  68. 68. GZ CURVE<br />
  69. 69. TRIM UPDATE<br /><ul><li>LCB At LWL = 0.72 m aft of amidship
  70. 70. LCG of total ship = 0.93 m aft of amidship
  71. 71. Displacement of the Ship = 74.68 tonne</li></ul>At LWL,<br /><ul><li> MCT1m = 141.16 tonne-m
  72. 72. C.F. = 1.08 m aft of amidship
  73. 73. Draft = 1.1 m</li></ul>[The value of LCB,MCT1m,C.F. are taken from the Hydrostatic Calculations earlier in the design procedure]<br />
  74. 74. TRIM UPDATE<br />Now,<br />Amount of Trim={(0.93-0.72)*74.68}/141.16 <br /> = 0.1111 m by stern <br />So,<br />Change in Trim aft= 0.05 m<br />Change in Trim Forward= 0.061 m<br />Therefore, resulting<br /> Draft Forward= 1.1-0.061 = 1.039 m<br /> Draft Aft= 1.1+0.05 = 1.15 m<br />
