Description

CROSS REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority to Japanese Patent Application No. 2022-096373 filed on Jun. 15, 2022. The entire contents of this application are hereby incorporated herein by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marine vessel including an attachment that is able to be attached and detached to and from the marine vessel. 2. Description of the Related Art As seen in many small marine vessels, marine vessels, to/from which attachments such as expansion type platforms, wake poles (poles for wakeboards) or tarps are able to be attached/detached, are known. For example, in Japanese Laid-Open Patent Publication (kokai) No. 2003-237683, a simple roof is able to be attached/detached to/from a hull. In addition, in Japanese Laid-Open Patent Publication (kokai) No. H05-085468, an awning is able to be attached/detached to/from a gate located at the rear portion of a hull. Furthermore, marine vessels are also known in which the state of the attachment is able to be changed, for example, between a used state and an unused state (a stored state) (see Japanese Patent No. 3174157 and Japanese Laid-Open Patent Publication (kokai) No. 2016-060475). However, when the marine vessel is navigating while the attachment is attached to the marine vessel, the feeling during maneuvering of the marine vessel and a navigation performance of the marine vessel may change. SUMMARY OF THE INVENTION Preferred embodiments of the present invention provide marine vessels that are each able to inform a vessel operator that an attachment is attached to the marine vessel. According to a preferred embodiment of the present invention, a marine vessel includes a hull and a controller configured or programmed to function as a judging unit to judge whether or not an attachment attachable and detachable to and from the hull is attached to the hull, and to function as a notifying unit that, in a case of being judged by the judging unit that the attachment is attached, execute a notification process to notify a vessel operator that the attachment is attached to the hull. According to a preferred embodiment of the present invention, in the case that the judging unit judges that the attachment that is attachable and detachable to and from the hull is attached to the hull, the notifying unit notifies the vessel operator that the attachment is attached to the hull. As a result, it is possible to inform the vessel operator that the attachment is attached to the marine vessel. The above and other elements, features, steps, characteristics and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments with reference to the attached drawings.

FIG. 4 is a schematic side view that shows a tarp in a used state. FIG. 5 is a schematic side view that shows the tarp in an unused state. FIG. 6 is a block diagram of a marine vessel maneuvering system included in the marine vessel according to the first preferred embodiment of the present invention. FIG. 7 is a flowchart that shows the flow of an attachment handling process. FIG. 8 is a schematic top view of a rear portion of a hull to which an expansion deck is attached according to a second preferred embodiment of the present invention. FIG. 9 is a schematic side view of the rear portion of the hull to which the expansion deck is attached. FIG. 10 is a block diagram of the expansion deck. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, a first preferred embodiment of the present invention will be described. FIG. 1 is a plan view of a marine vessel 11 according to the first preferred embodiment of the present invention. In FIG. 1, a portion of the marine vessel 11 is shown in an exposed view. The marine vessel 11 includes a hull 12 and a deck 13 disposed on an upper portion of the hull 12. The marine vessel 11 is, for example, a water jet propulsion boat. In the following description, as shown in FIG. 1, front, rear, left, and right directions refer to front, rear, left, and right directions of the hull 12, respectively. The left direction and the right direction are defined with reference to the hull 12 being viewed from the rear. A vertical direction is a direction perpendicular to a front-and-rear direction and a right-and-left direction.
