<P> Cathedral hulls became popular in the 1960s and 1970s , when the use of fiberglass made economical production of this hull - form possible . The undesirable aspects of the cathedral hull are greater weight and cost , pounding in rough water , and a boxy appearance . Their advantages include high waterplane area at rest ( good initial stability ) a dry ride in light chop , and reasonable fuel economy at planing speeds . In exposed waters this hullform has been almost totally replaced by the modified - vee and deep - vee hull forms . After a period of reduced popularity , they live on in modified form as `` deck boats '' which are very popular in the inland lakes and rivers . </P>
