WebThe stern sinkage is a combination of midship sinkage and stern-down trim, given by θ stern midships 2 L s =s + ( 6) with θ in radians. For the A3 hull at h/L =0.125, the stern sinkage reaches a maximum of around 2.8% of the waterline length just before 0Fh =1. . Note that, since the midship sinkage does not reach a maximum at exactly the ...
