Everything on board is very shipshape and carefully thought out, and it is not in the design of the machines alone but also in their details and accessories that one can trace the expert boat builder's hand. The two machines shown, the Channel type and the " Sea King" single-seater, are built along similar general lines, although differing in several details. The Supermarine hulls are. of elliptical or oval section, with a single- skin planking put on longitudinally, the butt joints of the planking occurring opposite thin longitudinal stringers. The whole is then covered with fabric. One of the advantages of this form of hull construction is that the boat possesses a great amount of flexibility, acting in fact as a huge shock-absorber.
