Test and trials of the H.S. Denison are described and the following conclusions are presented: 1) hydrofoil ships can operate at speeds in the order of twice that of conventional ships and subcavitiating foil systems can operate at speeds up to 60 knots; 2) hydrid surface piercing configurations with pitch augmentation can be expected to operate satisfactorily in rough water; 3) an operating hydrofoil ship with high useful load to gross displacement ratio can be developed; 4) large right angle drive transmissions, utilizing spiral bevel gears can be successfully developed for use with hydrofoil craft; and 5) retractable hydrofoils greatly expedite maintenance and reduce drag by keeping the foils free of growth, while permitting more flexible operation in shallow water.
