Abstract
PURPOSE: To prevent the contact of broken ice with the shells of a catamaran type hull, and to reduce the resistance of the hull by mounting Archimedean screws to the nose sections of each body of the hull and inducing the broken ice so that the ice passes and flows in an opening between each body by the revolution of the screws.
CONSTITUTION: The hull 8 near the waterline is formed in a catamaran type, and the Archimedean screws 9 are mounted to the nose sections of each body 8a of the hull 8. The Archimedean screws 9 have tapered shapes in which nose sections are tapered, and are turned in shapes that intrude into an ice board 13 by revolution in the arrow direction, and the hull 8 is stranded on the ice board 13 by the screw action, thus breaking the ice board 13. The resistance of the hull is reduced because the broken ice 13a is collected in the hull central direction by the revolution of the Archimedean screws 9 and passes and flows in the passage 14 at the same time.
