Abstract

A marine propulsion system having a simple configuration and high energy efficiency and a marine vessel having the same. A detonation device for generating a detonation wave and a detonation wave discharger for releasing a detonation wave generated in the detonation device into the water so as to propel the marine vessel. When a detonation wave generated in the detonation device is discharged into the water by the detonation wave discharger, the discharged detonation wave pushes against the water, so a thrust pushing against a hull is generated as a reaction to the pushing force. A large-scale mechanism such as a propulsion system using a mechanical drive mechanism such as a screw or a propulsion system for generating a high pressure gas by utilizing a compressor is not needed, so the configuration can be simplified. Further, the water is pushed away by the detonation wave, so turbulence becomes hard to occur in the water, and the loss of the energy due to turbulence can be greatly reduced.
