Question

A Mariner vessel, floating at a draft of 23'6", has a GM of 1.5 feet which does not meet the required GM standard. How far above the keel must 1,400 tons be loaded to increase the GM to 2.0 feet?

Answer 1

0.5 feet

Step-by-step explanation:

it is given that the martin floats at draft of 23'6"

GM=1.5

The load is given as follows

1400 tons is loaded as 2 feet above keel

1400 tons-----kg----2 feet

final kg =
`(final moment )/(final dispacement)`

`(weight)/(1400 kg)` =
`(kg)/(2 feet)` =
`(moment of keel )/(2800)`

final kg =
`(2800)/(1400)`=2 feet

final GM =2 feet-1.5 feet

=0.5 feet
