To provide a water jet propulsion boat efficiently using a water flow generated by an impeller.SOLUTION: A water jet propulsion boat includes a hull, a drive source, a power storage device, a jet propulsion mechanism, a power generation mechanism, and a controller. The hull has a water absorption port, a water ejection port, and a flow path communicating with the water absorption port and the water ejection port and including a main flow path extending at least from the water absorption port toward the water ejection port. The drive source is provided in the hull. The power storage device supplies electric power to the drive source. The jet propulsion mechanism has an impeller arranged in the main flow path for generating a water flow in the flow path by being activated by drive force of the drive source and has propulsion force for the hull generated by the water flow generated in the main flow path by the impeller. The power generation mechanism is provided in the flow path and generates power by using the water flow generated by the impeller. The controller charges the power storage device by power generated by the power generation mechanism.SELECTED DRAWING: Figure 4

    【課題】インペラによって発生された水流を有効に利用する水ジェット推進艇。【解決手段】水ジェット推進艇は、船体と、駆動源と、蓄電装置と、ジェット推進機構と、発電機構と、コントローラと、を備える。船体は、吸水口と、噴射口と、吸水口と噴射口とに連通する流路であって、少なくとも吸水口から噴射口に向かって延びるメイン流路を含む流路とが形成されている。駆動源は、船体に配置される。蓄電装置は、駆動源に電力を供給する。ジェット推進機構は、メイン流路に配置され、駆動源の駆動力により動作して流路に水流を発生させるインペラを有し、インペラによってメイン流路に発生された水流によって船体の推進力を発生させる。発電機構は、流路に配置され、インペラによって発生する水流を利用して発電を行う。コントローラは、発電機構が発電した電力によって蓄電装置を充電する。【選択図】図4
