Shallow-Draft Hydrofoil Motor Vessel for Passenger Service

摘要

Design improvement of a hydrofoil passenger boat are given. The design differences effect the propulsion unit and the rudder. As a result of the design changes, tested under operating conditions, the basic operational technical indices (useful load, speed, steering qualities, power expenditure) of the shallow-draft hydrofoil vessel were brought practically up to the indices of the standard hydrofoil boat. Eliminating the housing over the propeller and the installation of two rudders instead of one removed the tendency for cracks to form in parts of the rudder and propulsion units. The reliability of the shallowdraft hydrofoil boat became better than that of the standard hydrofoil boat, the propeller of which is not protected.
