<P> The term "cathedral hull" refers to the resemblance of a section through an inverted boat to that of a medieval cathedral . </P> <P> The cathedral hull configuration tends to result in a very broad bow; many such boats are completely rectangular . This provides the maximum cargo or working space for a given length and beam . The hull shape is also very stable compared to a conventional v - shaped bottom, and in either light chop conditions or above 40 knots or so is faster than a flat bottom, for the same weight, length and beam . </P> <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> <P> The Catheral hull design was originated by Naval Architect Richard C.
