<p>A fast marine craft suitable for operation in the range of Froude numbers between 0.5 and 1.0 has a hull which can be considered as being defined by a series of transverse spaced apart frames, the frames nearest the head of the craft being generally triangular in section and having slightly concave sides, and the frame shape flattening gradually to define a flat planning section aft of the midships frame and the base of the hull subsequently developing into a concave tunnel profile.</p> |
