Webhave to be reduced in order to gain from the trim. The wetted surface area is calculated for the vessel at rest, i.e. without dynamic sinkage and trim. The variation in wetted surface area due to trim relates in most cases to the large flat stern area and is relatively small. 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 ...
