Abstract: A device to moving a water shooter is described. The device may contain features that allow the device to travel submerged in a reservoir with a water shooter attached. The device may travel along a fixed track, rotational boom, or be free swimming in order to move the water shooter within the reservoir so that unique water effects may be achieved.

Abstract: A water delivery device that may be used in a water display is described. The device includes an orifice or outlet through which water is shot out. The shape and configuration of the water device may be varied to dynamically adjust the configuration of the water shot out from the device. For example, the water delivery device may shoot out water in the shape of a fan, and the width of the fan may be varied.

Abstract: An impingement fan water display that may be used in a water display is described. The device may include two nozzles that project streams of water towards each other in an intersecting trajectory and impinge upon each other. The angle of orientation of the nozzles in relation to each other may be varied to produce varying water stream fan widths and shapes. A plate may be located at or near the point of impingement.

Abstract: The invention provides for a versatile boat which is highly stable and maneuverable in a variety of water conditions. The boat is substantially symmetrical about a longitudinal, vertical plane and has a lower hull portion that is generally V-shaped in cross section. Connected to the lower hull portion is a generally inverted V-shaped upper hull portion which is interrupted in both the bow and stern by decks inclined toward the longitudinal plane. Positioned interiorly of the hull sections and extending substantially the length of the boat is an internal barge structure. The barge structure is spaced apart from the hull sections to define ballast compartments in between these structures. When flooded, the ballast compartments enable the boat to operate in a semi-submerged position while floating on the internal barge structure.
