TELFER, D.Sc., Ph.D., Vice-President SYNOPSIS.-/t is suggested that modern progress in ship design has been principally directed to improved smooth-water performance and not suffi- ciently to improved behaviour under adverse weather conditions.Such behaviour as is good is known as "sea-kindliness," a quality not to be confused with seaworthiness. Rolling considerations are used to introduce the subject of sea-kindliness. Sailing ships and steamers are compared and light versus concentrated cargoes are discussed.Various design aspects are mentioned.Next, pitching is considered in relation to cargo distribution and to external form. Particular attention is given to the modern fashion display in stem design, and a preference registered for the old-fashioned clipper stern as having scientific justification.Fine versus full cruiser sterns are discussed.
