Abstract: A reel system for managing a surf rope on a boat. The reel system comprises a retraction assembly, a rod and the surf rope. The boat comprises a cross bar, a stern, a port, one or more sides, a starboard, and a tower having a tower height. The surf rope comprises a rope height between the retraction assembly and a handle portion of the surf rope. The surf rope comprises a first end and a second end. The reel system comprises a system for positioning and managing the surf rope for a surfer. The reel system is configured to manage the surf rope by retracting and positioning the surf rope at one or more default rope positions when not in use and otherwise selectively allow the surf rope to rotate back for surfing. The one or more default rope positions comprise at least a first default rope position.

Abstract: A thruster assembly to create shaped waves in a water behind a boat for water sports, such as wake surfing. The thruster assembly comprises one or more thrusting channels, an outer body the outer body comprises a round surface in the form of a circular or elliptical cross-section. The outer body comprises an elongated elliptical cross-section being wider than it is tall. A thruster portion comprises a width, a height, and a depth. The outer body comprises an outer surface and an inner surface. The outer body comprises a round surface in the form of a circular or elliptical cross-section. The outer body comprises an elongated elliptical cross-section being wider than it is tall.

Abstract: A wake-modifying a surf tab that can be attached to a watercraft is disclosed. That surf tab includes a control plate assembly, a mounting hinge for attaching the control plate assembly to a watercraft, a hydro-thruster assembly, and a separation hinge attaching the control plate assembly to the hydro-thruster assembly. Also included is an actuator attached to the control plate assembly which connects the control plate assembly to the watercraft such that the actuator can control the angle between the control plate assembly and the watercraft. a length adjustable control rod assembly connects the control plate assembly to the hydro-thruster assembly. The control rod assembly adjusts the angle between the control plate assembly and the hydro-thruster assembly. In use, the length of the actuator and the length of the control rod assembly can change the flow of water from the hydro-thruster assembly to modify a wake created by a watercraft.

Abstract: A wake-shaping system comprising a one or more surf tabs attached to a watercraft. The one or more surf tabs comprise at least a first surf tab. The first surf tab comprises an upper plate, a mounting hinge, a lower portion, a one or more mounting brackets comprising at least a first mounting bracket. A hydro-thruster assembly having a one or more hydro-thruster diversion fins. further, the first surf tab comprises a leading edge, a trailing edge, an interior side, an exterior side, a top side and a bottom side. The upper plate is rotatably attached to a portion of the watercraft with the mounting hinge. The watercraft travels through a water in a direction of travel. The leading edge comprises a forward portion of first surf tab relative to the direction of travel and the trailing edge comprises a rearward portion.
