ABSTRACT OF THE DISCLOSURE The present invention relates to a device used in jet- propelled gliding boats for preventing floating obstacles from being drawn in, wherein a scope gate for preventing entry of garbage, seaweed, fishing fines and other floating obstacles is attached to a water intake port formed in the bottom surface of a boat body, and the water drawn from the water intake port is accelerated by an impeller housed in a water intake duct and spouted rearwardly of the boat body, the device being characterized in that the scope gate is in lattice form composed of a pelf of attacking seats associated with the bottom surface of the boat body and a single longitudinal partition wall extending along the travel center fine of the boat body or a pair of longitudinal partition walls extending parallel with the travel center fine of the boat body, interconnecting the attacking seats, substantially the latter half or halves of the longitudinal partition wall or walls project downward by a fixed amount beyond the bottom surface of the boat body, while a transverse partition wall is disposed in the intermediate portion or portions of the projecting latter half or halves to assume an inclined state sloping rearwardly upward at a fixed angle, whereby a larger space for water intake is defined between the transverse partition -26- wall and the front attaching seat and a smaller space for water intake is defined between the transverse partition wall and the rear attaching seat. -27-
