(ii) The following bunkers were worked of! during the passage.
Required the new GM, assuming the K M for the new draught to be
24 feet:—
Tons	300     200     500
V.Ca.—Feet         24       26       18
Answer.—G M 1*2 feet.
25. Example—From the following information construct a cargo
plan and fill in the column headed "Moments," also the blank spaces
and compute the ship's G M when loaded.
Given light displacement 2000 tons, height of centre of gravity
(K G), 12 feet height of metacentre (K M) 17 feet when loaded with
cargo as indicated below.
