摘要:
A jet-propelled craft includes a hull, an engine installed within the hull, a duct positioned in the stern area of said hull, and an impeller which is turned by the rotational force of the engine to create a jet stream within the duct. The craft also includes left and right secondary water-intake openings on the bottom of the hull which are positioned a specific distance apart on the left and right in the hull, the duct including branches connected to the left and right secondary water-intake openings. By equipping the secondary water-intake openings with a valve which closes when a sharp turn is made in the above mentioned boat and the valve is on the outside with respect to the direction of the turn, air is prevented from entering the outside secondary duct and a loss of propulsive force is prevented.
