Question

Effect of increasing beam andfreeboard on ship stability

Answer 1

To investigate the effect of beam and freeboard on stability, it is necessary to assume the stability curve for a particular vessel in a particular condition of loading. ... With increased freeboard GMT and GZ increase, range of stability increases, deck edge immerses later at greater θ, and KB decreases.

Answer 2

Answer:

With increased beam

• transverse GM and GZ increase.

• Range of stability increases.

• Deck edge immerses earlier.

• KB remains similar.

With increased freeboard

• transverse GM and GZ increase.

• Range of stability increases.

• Deck edge immerses later at greater theta(angle of heel)

• KB decrease.
