Abstract
PURPOSE: To prevent a craft from stranding by such a construction that the lower end of a rudder is projected from the lowermost point of the hull when it is positioned downward in the water, so that the rudder emits alarm just when the craft is running in a shallow water.
CONSTITUTION: When a water jet craft with this construction is just running into a shallow water, the lower end 20c of the rudder 20 will touch the ground before the bottom of the craft touches the ground. This touch with the ground causes a noise with the rudder 20 as well as a light shock to the water jet craft 10, whereby the operator can know that the craft 10 is just running in a shallow water. The rudder 20 is to be so designed as to shift upward against the spring 25 force when it runs against any obstacle to prevent breakage and also as to be reinstated automatically to its normal hangdown position to continue sailing.
