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 a notifying unit to, 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. ### Claim 2 (depends on 1) The marine vessel according to claim 1, wherein, in the case of being judged that the attachment is attached, the notifying unit is configured or programmed to execute the notification process in response to a start of a propulsion device that applies a thrust to the hull. ### Claim 3 (depends on 1) The marine vessel according to claim 1, wherein the notifying unit is configured or programmed to execute the notification process by at least one of a sound or a display. ### Claim 4 (depends on 1) The marine vessel according to claim 1, wherein in the case of being judged that the attachment is attached, the judging unit is configured or programmed to further judge a state of the attachment; and the notifying unit is configured or programmed to execute the notification process in a mode corresponding to the judged state. ### Claim 5 (depends on 4) The marine vessel according to claim 4, wherein the state of the attachment is whether the attachment is in a used state or in an unused state; and the notifying unit is configured or programmed to execute the notification process in a different mode depending on whether the attachment is in the used state or in the unused state. ### Claim 6 (depends on 1) The marine vessel according to claim 1, wherein the controller is further configured or programmed to function as a control unit to, in the case of being judged by the judging unit that the attachment is attached, execute a limiting process to limit a function related to navigation of the hull. ### Claim 7 (depends on 6) The marine vessel according to claim 6, wherein, in the limiting process, the control unit is configured or programmed to limit at least one of a maximum speed or a maximum acceleration of the hull. ### Claim 8 (depends on 6) The marine vessel according to claim 6, further comprising: a propulsion device to apply a thrust to the hull and including a driving source; and in the limiting process, the control unit is configured or programmed to limit a maximum rotation number of the driving source. ### Claim 9 (depends on 6) The marine vessel according to claim 6, further comprising: a propulsion device to apply a thrust to the hull and including an engine; and in the limiting process, the control unit is configured or programmed to limit a maximum opening of a throttle in the engine. ### Claim 10 (depends on 6) The marine vessel according to claim 6, wherein in the case of being judged that the attachment is attached, the judging unit is configured or programmed to further judge whether a state of the attachment is a used state or an unused state; and in the limiting process, in a case that the state of the attachment is the used state, the control unit is configured or programmed to limit the function more than in a case that the state of the attachment is the unused state. ### Claim 11 (depends on 6) The marine vessel according to claim 6, wherein in the limiting process, the control unit is configured or programmed to limit at least one of a maximum speed or a maximum acceleration of the hull; and in the limiting process, in a case that a state of the attachment is a used state, the control unit is configured or programmed to cause at least one of the maximum speed or the maximum acceleration of the hull to be lower than in a case that the state of the attachment is an unused state. ### Claim 12 (depends on 1) The marine vessel according to claim 1, wherein the attachment is an object on which a person is able to board; in the case of being judged that the attachment is attached, the judging unit is configured or programmed to further judge whether or not a person is on the attachment; and the notifying unit is configured or programmed to execute the notification process in different modes in a case of being judged that a person is on the attachment and a case of being judged that a person is not on the attachment. ### Claim 13 (depends on 12) The marine vessel according to claim 12, wherein the controller is further configured or programmed to function as a control unit to, in the case of being judged by the judging unit that the attachment is attached, execute a limiting process to limit a function related to navigation of the hull; and in the limiting process, in the case of being judged that a person is on the attachment, the control unit is configured or programmed to limit the function more than in the case of being judged that a person is not on the attachment. ### Claim 14 (depends on 12) The marine vessel according to claim 12, wherein the attachment is attachable and detachable to and from a rear portion of the hull. ### Claim 15 (depends on 12) The marine vessel according to claim 12, wherein the attachment expands an area at a rear portion of the hull. ### Claim 16 (depends on 13) The marine vessel according to claim 13, wherein in the limiting process, the control unit is configured or programmed to limit at least one of a maximum speed or a maximum acceleration of the hull; and in the limiting process, in the case of being judged that a person is on the attachment, the control unit is configured or programmed to cause at least one of the maximum speed or the maximum acceleration of the hull to be lower than in the case of being judged that a person is not on the attachment. ### Claim 17 (depends on 13) The marine vessel according to claim 13, further comprising: a propulsion device to apply a thrust to the hull and including a driving source; and in the limiting process, the control unit is configured or programmed to limit a maximum rotation number of the driving source. ### Claim 18 (depends on 13) The marine vessel according to claim 13, further comprising: a propulsion device to apply a thrust to the hull and including an engine; and in the limiting process, the control unit is configured or programmed to limit a maximum opening of a throttle in the engine. ### Claim 19 (depends on 1) The marine vessel according to claim 1, wherein the attachment is an object that is visible when the hull is viewed from a horizontal direction, or an object to come into contact with a surface of the water during navigation.
