Abstract

A jet propulsion watercraft includes a vessel body, a jet pump that is disposed at the vessel body and that includes a water jet opening, and a first guide that is attached to the vessel body. The jet pump generates a thrust by sucking in water existing around the vessel body and jetting the water from the water jet opening. The first guide receives water flowing on a lateral side of the vessel body and generates a downforce that generates a wake behind the vessel body.
