314 Ship Stability for Masters and Mates
Exercise 36
1 A river is 150m wide and has 12m depth of water. A passenger liner having a breadth of 30 m a static even-keel draft of 10 m and a Cb of 0.625 is proceeding along this river at 8 kts. She meets an approaching general cargo vessel having a breadth of 20 m, a static even-keel draft of 8 m and a Cb of 0.700 moving at 7 kts.
Estimate the maximum squats of each vessel when their amidships are transversely in line.
2 With the aid of sketches, de®ne Interaction and list how its effects may be limited. Show clearly how Interaction and transverse squat are inter-related.
