Watercraft

Abstract

A watercraft includes a hull, a propulsion device to generate a propulsive force to propel the hull, a trim adjuster to change a trim of the hull, a mode setter operable by a user to selectively set a watercraft movement characteristic mode, and a controller configured or programmed to control the propulsion device according to a propulsive force control characteristic defined for the mode set by the mode setter and to control the trim adjuster according to a trim control characteristic defined for the mode set by the mode setter.

What is claimed is: 
     
         1 . A watercraft comprising:
 a hull;   a propulsion device to generate a propulsive force to propel the hull;   a trim adjuster to change a trim of the hull;   a mode setter operable by a user to selectively set a watercraft movement characteristic mode; and   a controller configured or programmed to control the propulsion device according to a propulsive force control characteristic defined for the mode set by the mode setter and to control the trim adjuster according to a trim control characteristic defined for the mode set by the mode setter.   
     
     
         2 . The watercraft according to  claim 1 , wherein the propulsive force control characteristic includes at least one of an upper limit watercraft speed or an upper limit watercraft acceleration rate. 
     
     
         3 . The watercraft according to  claim 2 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes a first mode in which the propulsive force control characteristic includes the upper limit watercraft speed set to a first value, and a second mode in which the propulsive force control characteristic includes the upper limit watercraft speed set to a second value that is smaller than the first value. 
     
     
         4 . The watercraft according to  claim 3 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter further includes a third mode in which the propulsive force control characteristic does not include the upper limit watercraft speed. 
     
     
         5 . The watercraft according to  claim 1 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes a fourth mode in which the trim control characteristic includes the trim of the hull being changeable when the watercraft is driven in the fourth mode. 
     
     
         6 . The watercraft according to  claim 1 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes a fifth mode in which the trim control characteristic includes the trim of the hull being maintained constant when the watercraft is driven in the fifth mode. 
     
     
         7 . The watercraft according to  claim 1 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes a sixth mode in which the trim control characteristic includes the trim of the hull being changeable according to a state of the watercraft, and a seventh mode in which the trim control characteristic includes the trim of the hull being maintained constant irrespective of the state of the watercraft. 
     
     
         8 . The watercraft according to  claim 1 , wherein the watercraft is a planing watercraft. 
     
     
         9 . The watercraft according to  claim 8 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes an eighth mode in which the trim control characteristic includes the trim of the hull being set to a first trim when a speed of the watercraft falls within a non-planing speed range, and the trim of the hull being set to a second trim that is greater than the first trim when the speed of the watercraft falls within a planing speed range. 
     
     
         10 . The watercraft according to  claim 1 , wherein the propulsion device is a waterjet propulsion device. 
     
     
         11 . The watercraft according to  claim 10 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes a ninth mode in which the trim control characteristic includes the trim of the hull being fixed to direct a waterjet jetted from the waterjet propulsion device downward with respect to a water surface. 
     
     
         12 . The watercraft according to  claim 1 , further comprising:
 a movable sponson attached to the hull; and   a sponson actuator to move the sponson; wherein   the controller is configured or programmed to control the sponson actuator according to a sponson control characteristic for the mode set by the mode setter.   
     
     
         13 . The watercraft according to  claim 12 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes a tenth mode in which the sponson control characteristic includes the sponson being maintained at a fixed position when the watercraft is driven in the tenth mode. 
     
     
         14 . The watercraft according to  claim 12 , wherein the watercraft movement characteristic mode to be selectively set by the mode setter includes an eleventh mode in which the sponson control characteristic includes a position of the sponson being changeable when the watercraft is driven in the eleventh mode. 
     
     
         15 . The watercraft according to  claim 1 , further comprising a display to display watercraft maneuvering information and change a display color of a predetermined display area thereof according to the mode set by the mode setter.
