Definitions

  • the invention relates to a jet propulsion small boat comprising a deck member and a hull member, both integrally formed of synthetic resin such as FRP, and bonded with each other at their fringe portions, said deck member comprises bulwarks formed at its fringe portions except the stern end of the deck member, a seat end and an operating handle stand, both projectionally formed on the hull centre line, said deck member comprising decks formed at both sides of the seat stand, such as fishing with the boat drifting on the sea surface.
  • synthetic resin such as FRP
  • a small jet propulsion boat which is engined for gliding on the water surface like a motor-cycle type jet boat. Since such a jet propulsion boat is used for practising various motions while gliding at a high speed on the water surface, it is provided with seats including, for example, a bench seat on the hull centre line, and an operating handle on its front portion to be operated by a rider sitting astride the seat with his feet placed on the decks on both sides thereof.
  • jet propulsion boat practises various motions while gliding on the water surface at a high speed and thus waves are frequently apt to dash over the boat, it is necessary for the water thrown up on to the boat to be readily rejected and removed from the boat's deck surfaces.
  • a jet propulsion boat is nowadays more and more utilised not only for gliding on the water surface but also for other purposes such as fishing, leaving the boat drifting on the sea surface, it is desirable for the rider on the boat to be able to move about on it easily and without discomfort.
  • the afore-mentioned object is attained in that another deck is provided in front of the operating handle stand, all of these decks are integrally continuously formed with each other as a substantially single plane with their stern ends opened in order to allow water thrown up on board to be smoothly rejected from the rear end portions of the decks to their stern ends without staying on board, and a seat is provided in front of the operating handle stand.
  • the decks are formed continuously integrally with each other as a generally single plane with the stern end of the boat's deck being unrestrictedly open, water thrown up on board can promptly be rejected from the boat's decks flowing off the stern ends thereof and, moreover, it is very easy for the rider or riders to move about the deck.
  • the hull member comprises a bottom plate, side plates and a stern plate
  • the deck member comprises rising portions formed at its fringes except at the stern end portion of the deck member, said rising portions having their upper end portions folded back put upon and bonded with the upper end portions of the hull side plates to form bonded portions with said rising portions of the deck member and said side plates of the hull member defining spaces therebeteween to establish said bulwarks, substantially supporting an increased stability of the boat.
  • a plurality of seats or a bench seat and another seat are respectively provided to the rear and front portions of the seat stand, the latter being integrally provided with the deck portions.
  • the boat can conveniently be used for fishing, leaving the boat drifting, designing said bulwarks to form footings while setting the seats higher than the bulwarks.
  • a particular increased buoyancy can be obtained if the hull member and the deck member including the seat stand, operating handle stand and bulwarks are designed to form a hermetically sealed space to define displacement volume.
  • said continued decks which form a generally single open-ended plane at the stern end portion of the boat, are set to be slightly inclined rearwardly when the boat is under way to promote the rejection of water from the deck.
  • a compacted structure of the boat can be obtained in that an engine room is found beneath the operating handle stand and the seat stand adapted to receive at least an engine and a fuel tank, with the engine being provided to rotate a propeller to suck in water through a water suction opening at the hull bottom and to inject it backwards in a deisred direction through a water passage and then through a horizontally swingable nozzle at the stern of the boat to produce a propelling force and a turning force, respectively.
  • the boat hull 1 is composed of a hull member 2 and a deck member 3 both integrally formed from synthetic resin such as FRP and bonded with each other at their respective fringe portions.
  • the portion surrounded by the hull member 2 and the deck member 3 is formed as a hermetically sealed space to define an appropriate displacement volume.
  • the hull member 2 has a bottom plate 20, side plates 22 and a stern plate 24 and the deck member 3 comprises rising portions 31 erecting at its fringes with the exception of the stern end of the boat, with the upper end portions of said rising portions 31 being folded back, put upon and bonded with the upper end portions of the hull side plates 22 to form the bonded portions 23.
  • These rising portions 31 and the associated side plates 22 form spaces therebetween and thus establish bulwarks 8.
  • the deck member 3 is provided with a seat stand 4 and an operating handle stand 61, both projectingly formed on the hull centre line and comprises decks 30 with open stern ends formed on both sides of these stands 4, 61 between the bulwarks 8 and these stands 4, 61 and, finally, a deck 33 is formed in front of these stands. All of these decks are integrally continuously formed with each other as a generally single plane.
  • On the above-mentioned operating handle stand 61 is mountd an operating handle 60 and on the rear and front portions of the seat stand 4 are formed seats 50, preferably designed as a bench seat, and a seat 51, respectively.
  • an engine room in which are arranged an engine 14, a fuel tank, etc, and by this engine 14 a propeller (not shown) is rotated to suck in water through the water suction opening 36 at the hull bottom and inject it backwards in a desired direction through the water passage 37 and then throughthe horizontally swingable nozzle 38 at the stern to produce a propelling force and a turning force.
  • a propeller (not shown) is rotated to suck in water through the water suction opening 36 at the hull bottom and inject it backwards in a desired direction through the water passage 37 and then throughthe horizontally swingable nozzle 38 at the stern to produce a propelling force and a turning force.
  • the space on board can be effectively utilised by two riders by seating both riders fore and aft astride the seat 50 as shown in Fig 4 while gliding ordinarily, and also by seating one rider forward on the front seat 51 with his feet placed on the deck 33 and the other rider rearward on the seat 50 as shown in Fig 5, while lying at anchor offshore for fishing or the like.
  • the rider can move about on boad the boat according to this invention very easily because the decks 30 and 33 continue to each other as a generally single plane.
