Abstract: An object is to provide a technique related to a small watercraft that can prevent water from entering an inboard section through air intake ports. A small watercraft for leisure use is configured to obtain thrust by driving a propeller with an engine serving as a power source and includes an air intake port configured to introduce air into an engine room in an inboard section from the outside, and a radar arm configured to support a radar. The air intake port is positioned on the inner side with respect to the radar arm.

Abstract: A space of an inboard section can be effectively used and thus a compartment can have a larger space (living space) compared with a configuration in which walls (inner wall materials) stand in a vertical direction in the inboard section. An object is to provide a technique related to a watercraft. A watercraft 1 for leisure use that is used for sports, recreations, and the like includes a compartment formed with an inner wall material 54 provided on an inboard section in such a manner as to be curved in accordance with a shape of the inboard section.
