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.

Claims (19)
