Abstract: An inflatable boat comprising an inflation structure which in turn has a drop stitch structure which is made of upper and lower fabric layers and also a core section made up in an array of threads extending throughout the drop stitch structure. The outside contour comprises a watertight/air tight sidewall enclosing the drop stitch structure and there is a seating compartment within the drop stitch structure and an interior wall sealing off the inside of the flotation structure.
Abstract: A water ride includes a flume (10) defining a ride path. Patrons of the ride travel in rafts (24) along the flume (10) with the rafts riding on a thin layer of water introduced into the flume. To induce the rafts (24) to spin at desired locations in a controlled fashion, the rafts each include raft features (30) located on a bottom surface (32) of the raft. Flume features (34) are positioned at desired locations along the ride path in position to make contact with the raft features (30). This contact between the raft features (30) and the flume features (34) induces a controlled spin to the raft (24). The raft features (30) preferably include projections (36) extending downwardly from the bottom surface (32) of the raft at locations offset from a raft center of rotation. The flume features (34) preferably comprise alternating depressions (38) and ridges (40) extending transversely to the ride path along one side of the flume (10).
