While the sinkage and trim of a displacement ship does change with speed, the changes are relatively small and do not result in large changes to their waterline length and wetted surface area. Planing craft, …

WebJan 8, 2024 · A comprehensive validation study has been performed for drag, trim and sinkage values by unsteady RANS simulations using sea trial data at full-scale. In the study of Broglia et al., 5 the interference phenomenon has been investigated for Delft 372 benchmark catamaran by using RANS based solver. 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 ...
