Ans. KG 6:06 m as shown in sketch on page 240.
Example 2
When a mass of 10 tonnes is shifted 12 m, transversely across the deck of a ship with a GM of 0.6 m it causes 0.25 m de¯ection in a 10 m plumb line. Calculate the ship's displacement.

Summary
Every new ship should have an Inclining Experiment. However, some shipowners do not request one if their ship is a sister-ship to one or more in the company's ¯eet.
If a ship has undergone major repair or re®t, she should then have an Inclining Experiment to obtain her modi®ed Lightweight and centre of gravity (VCG and LCG).
