BOAT HAVING AN IMPROVED ABILITY TO GET ON PLANE AND IMPROVED METHOD OF GETTING A BOAT ON PLANE

摘要

A boat includes at least three trim devices positioned aft of the boat's transom. To improve the boat's ability to get on place, each trim device is initially positioned to a deployed position. The speed of the boat is then determined as the boat gains speed. When the speed of the boat exceeds a first predetermined threshold, the first trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a second predetermined threshold, the second trim device is moved from the deployed position to a non-deployed position. When the speed of the boat exceeds a third predetermined threshold, the third trim device is moved from the deployed position to a non-deployed position. At least one of the first, second, and third predetermined thresholds is different from the other two of the first, second, and third predetermined thresholds.

1. A boat comprising:
a hull including a bow, a transom, and port and starboard sides; at least three trim devices positioned aft of the transom, a first one of the trim devices being provided on a port side of the boat's centerline, a second one of the trim devices being provided on a starboard side of the boat's centerline, and a third one of the trim devices being provided between the first and second trim devices, each of the trim devices being moveable between a deployed position and a non-deployed position; a plurality of drive mechanisms, each drive mechanism configured to move a corresponding trim device between the deployed position and the non-deployed position; a speed sensing device configured to determine the speed of the boat; and a controller configured to:
actuate the plurality drive mechanisms to move each of the at least three trim devices to the deployed position;receive the speed of the boat from the speed sensing device;determine when the speed of the boat exceeds a first predetermined threshold;actuate the drive mechanism corresponding to the first trim device to move the first trim device from the deployed position to the non-deployed position when the speed of the boat exceeds the first predetermined threshold;determine when the speed of the boat exceeds a second predetermined threshold;actuate the drive mechanism corresponding to the second trim device to move the second trim device from the deployed position to the non-deployed position when the speed of the boat exceeds the second predetermined threshold;determine when the speed of the boat exceeds a third predetermined threshold; andactuate the drive mechanism corresponding to the third trim device to move the third trim device from the deployed position to the non-deployed position when the speed of the boat exceeds the third predetermined threshold, wherein at least one of the first, second, and third predetermined thresholds is different from the other two of the first, second, and third predetermined thresholds.
