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.

A towboat hull configured to shape a desired wake shape by creating an adjustable dual side surf wake as the vessel travels through water. Controlled shaping of the wake is achieved by a secondary thrust flow redirector unit that has flow redirectors that redirect the thrust flow from a propeller as the towboat moves in a forward direction. The flow redirectors can create a single side surf wake on either side of the towboat or can simultaneously create an side surf wakes on both sides of the towboat. The adjustable flow redirector can create side surf wake with a controlled shape that is desirable for wake surfing.

The invention relates to a device for producing a stern wave on a watercraft, in particular a sports boat, for wakesurfing and/or wakeboarding on the stern wave, comprising at least one pivoting deflector that can be pivoted out laterally, in particular respectively on a right-hand and left-hand lateral region of the hull of the watercraft, having an arranging means, in particular hinge means, on a lateral hull region of the watercraft, in particular in the region of the stern, wherein a stern wave for wakesurfing and/or wakeboarding can be formed by the pivoting deflector in the pivoted-out state, and an integration region for the pivoting deflector in the lateral hull region of the watercraft, such that the hinge means is substantially integrated in the hull region of the watercraft in the pivoted-in stage, to adapt and/or continue a hull outer line in the lateral hull region of the watercraft.

A water flow deflection device attached to a side of a watercraft to enhance the watercraft's wake. The device having a narrow, elongated base with two ends and a base width, the base aligned along the side of the watercraft when the device is attached to the watercraft. A deflector attached to the base between the two ends and having a face spanning between a leading end and an opposing end, the leading end extending outwardly from the base. The deflector face having a surface area configured to deflect water and a deflector width greater than the base width. The base removably attachable to the watercraft by a plurality of suction cup assemblies, wherein a greater number of suction cup assemblies located between the first end and the leading end of the deflector than between the second end and the leading end of the deflector.

A wave-generating watercraft includes a craft body having an installation space. A telescopic drive is mounted within the installation space. A pivot seat is mounted on the craft body within the installation space. A wave-forming block is driven by the telescopic drive to move between extended and retracted positions, and has an outside block face and an inside block face. When the wave-forming block moves to the retracted position, the inside block face is pulled by the telescopic drive, and the outside block face moves to the installation space. When the wave-forming block moves to the extended position, the inside block face rotates away from the telescopic drive, and the outside block face protrudes from the installation space.

A recreational sport boat includes a hull having starboard and port sides and a transom, a generally horizontal platform, and a pair of wake-modifying devices positioned aft of the transom. The generally horizontal platform extends aft of the transom and is configured to support a human weighing at least 100 lbs. on an upper surface thereof. The pair of wake-modifying devices are attached to the platform. One of the wake-modifying devices is positioned on a port side of the platform's centerline, and another of the wake-modifying devices is positioned on a starboard side of the platform's centerline. Each wake-modifying device is moveable between a non-deployed position and a deployed position in which the wake-modifying device is angled downwardly at an angle relative to the top surface of the generally horizontal platform.
