Embodiment Construction

[0020] The following description is to better embody the present invention, but any change or modification according to the description is still considered within the protection of this patent.

[0021] Such as Figure 1-4 As shown, the kayak 10 includes a sealed hull portion 12, which is made of plastic through a seamless mold. In order to improve the strength of the hull, it is preferable to use a synthetic material with added glass fiber, carbon fiber or Kevlar plastic. Gel coats can be formed from sheets of HDPE.

[0022] The upper surface 15 of the hull has a recessed portion 14 to accommodate the driver facing forward and a manually controlled control lever 16 (i.e. joystick), the driver straddles the control lever 16 with his feet on his feet respectively. Step 17, 18. The part between the upper surface 15 and the lower surface 17 of the hull 12 is filled with a material 20 for strengthening, reinforcing and hardening the hull. Filling material 20 may be formed or ex...

Abstract

The invention discloses a water jet propelled ship, comprising a sealed ship hull, an engine cabin and a control lever; wherein, the sealed ship hull comprises an upper surface and a lower surface; the engine cabin with a propelling and operating system is behind the sealed ship hull; water is introduced by a blade propeller of an engine of the system from a water inlet and ejected through the pressure applied by a direction-adjustable jet pipe; the control lever on the upper surface is used for controlling an engine accelerator and the direction of the jet pipe. With an engine propeller system of a kayak provided by the invention, drivers can conveniently, freely and leisurely drive the ship for amusement; the ship hull is sealed, the buoyancy is strong and the vibration is low; water can not enter into the engine cabin in case the ship is straightly sunk in the water or overturned, thereby ensuring normal operation of the engine when the ship is turned to upright or normal position and floated on the water.

Description

technical field [0001] The present invention relates to a water jet propelled boat. Specifically, an inflatable boat that is powered by an engine and has a hull where the driver sits and controls speed and direction. Background technique [0002] Traditional kayaks typically provide one or more cabin seats for one to three drivers and are rowed by oars. A waterproof cover is used to prevent water from entering around the cabin seat, and also to prevent the boat from being flooded when the boat is turned over and turned upright. [0003] There is a growing popularity of recreational "sit-in-the-front" kayaks that differ from traditional kayaks in that they have a fixed rudder that can be steered, and water can enter the cabin through holes or pipes and then enter the bottom of the hull. The kayak is usually designed with single or double paddles, which are popular with anglers and divers because the rider can easily enter or exit the water by changing the sitting position. ...
