Publication number: 20220089258Abstract: A boat includes a propulsion device and a surf device. The propulsion device is configured to move the boat in a forward direction through a body of water to generate a wake having a port-side wave and a starboard-side wave. The surf device includes an inlet, an impeller, and an outlet. The surf device is configured to draw water from the body of water through the inlet, accelerate the water by rotating the impeller, and discharge the accelerated water through the outlet to create a surfable wake.Type: ApplicationFiled: September 23, 2021Publication date: March 24, 2022Inventors: Michael J.

Publication number: 20210300505Abstract: 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.Type: ApplicationFiled: June 14, 2021Publication date: September 30, 2021Inventors: Matthew J.
