Abstract : A study of the change in water-surface profile with Froude number near the stern of a Series-60 model, the shear-stress distribution on the after body, and a discussion of the possible laminar boundary-layer effects are presented. The results suggest that the sinuous trend of the viscous-drag curve is attributable to the change in surface configuration near the stern and the shear-stress distribution on the ship hull, and cannot be attributed to the presence of a laminar boundary-layer.
