Formula for calculating Squat as provided to me
Cb x Speed squared / 100 = Squat
Therefore a vessel with a Block Coefficient at current draught of 0.9
At 4kn = 0.144m
At 8kn = 0.576m
At 12kn = 1.296m
At 16kn = 2.304m
At 20kn = 3.600m
I am aware that there are several formulas around and find this one a bit much. Check your ISM to see what you were given by your architect.
