Abstract: A pulsation dampener includes: a centerbody assembly having: a chamber including a first opening bounded by a wall defining a first surface; an outlet port communicating with the chamber; an inlet port communicating with the chamber; a flexible first diaphragm, wherein a perimeter of the first diaphragm is bonded to the first surface forming a seal that blocks the passage of fluid; a first cap disposed adjacent the first diaphragm, defining a first cavity between the first cap and the first diaphragm; an inlet orifice formed in the first cap communicating with the first cavity; an exhaust orifice formed in the first cap communicating with the first cavity; and a valve seat disposed in the first cavity in fluid communication with the exhaust orifice. The first diaphragm is moveable between an open position spaced away from the valve seat, and a closed position sealed against the valve seat.

Abstract: A pontoon boat assembly includes at least two outer pontoon floats and at least one center pontoon float. A deck is supported above the floats. A propulsion system in the preferred form of a V-drive with a rear-facing propeller is provided for moving the pontoon boat across a body of water and causing wakes to trail behind the pontoon float in the path of the pontoon floats. At least one wake panel is supported off a stern end of at least one of the outer pontoon floats and is slideable to a lowered position for selectively engaging the body of water and altering the trailing wake to shape the wake. At least one hydrofoil is engagable with the body of water for drawing the stern end of the boat downwardly during propulsion of the pontoon boat to increase the size of the shaped wake.

Abstract: A variable use pontoon boat configured to operate in both a high speed condition and an improved wake-profile condition is provided. The boat includes a pair of outer pontoons that flare outward in the rearward direction. A rear section of the outer pontoons has a width that is greater than its height. An inclined bottom surface is defined by the outer pontoons. The bottom surface is inclined upward in the rearward direction, and may be inclined laterally upward. The system may include a center pontoon that flares outward in the rearward direction. The center pontoon and the outer pontoons may be spaced apart at a decreased distance at the rear of the boat relative to the front of the boat, such that water is blocked at the rear of the boat and displaced downward. A pair of wake panels may be disposed at the rear of the outer pontoons, and the wake panels may be individually and selectively actuated downward into the water to enhance the wake profile and retracted upward at high speeds.

Abstract: A system for enhancing a wake profile produced by a pontoon boat is provided. The system includes a pair of ramps attached to the bottom of a platform supported by at least two pontoons. The ramps may be oriented downward with a rear end of the ramp disposed in the water between the pontoons. The water flowing between the pontoons is displaced downward by the ramps, thereby increasing water displacement and directing the water to produce an improved wake profile. Downforce may be applied to the boat by one or more wake plates, with a faceted portion of the wake plate facing forward and upward, such that when water impacts the faceted portion a downforce is provided. The wake plates may be attached to the ramps or may be separate from the ramps.

Abstract: An insulated beverage container wrap is provided. It has a typically cylindrical body having an upper perimeter defining a substantially opened top, side walls, and a bottom wall defining a substantially closed bottom. A lid having a lower perimeter defining a substantially open bottom, a top wall defining a substantially closed top, and side walls is provided. A hinge connects side walls adjacent the lid of the lower perimeter and the body upper perimeter for allowing the lid to move between a substantially open position allowing access to a beverage contained within the body and a substantially covered position.
