A ship goes from water of RD 1.008 to SW. Find the change in draft , if her FWA is 180mm, and state whether it would be sinkage or rise.
Solution :
FWA = 180mm = 18cm
We can calculate :
Change in draft =
(Change in RD )x(FWA)
0.025
= (1.008 – 1.025 ) x 18 / 0.025
=(0.017 x 18)/0.025
= 12.24c
= 0.12m
Here , Change in draft is 0.122m and it will be rise.

A vessel goes from water of RD 1.010 to FW. If her FWA is 160mm, State whether she would sink or rise and by how much.
Solution :
FWA = 160mm = 16cm
We can calculate:
Change in draft =
(Change in RD )x(FWA)
0.025
= (1.010 – 1)x 16 /0.025
= 0.01 x 16 /0.025
= 6.4 cm
= 0.064 m
Here change in draft would lead to sinkage.
A ship loads in fresh water to her salt water marks and proceeds along a
river to a second port consuming 20 tonnes of bunkers. At the second port,
where the density is 1016 kg per cu. m, after 120 tonnes of cargo have been
loaded, the ship is again at the load salt water marks. Find the ship’s load
displacement in salt water.
Joe Bee. Can you please send me the solved question of the above question you posted. please
A mariner Enters port with 17,700 tons displacement,KG=28 feet, and GG=1.05 feet.A piece of Heavy machinery which weighs 180 tons is lifted by shore based cranes and placed on death so that its centre of gravity is 47 ft above the ship Khel and 19 feet two star board of centerline what will be the final mean draught gvm and angle of list when loading is complete?
