A water ride for transporting ride participants between portions of a water attraction disposed at different heights, for example, pools situated at various levels in a water leisure park, includes an outer support tube within which a hollow spiral coil (screw) is constructed internally of the tube and securable to the tube. Advantageously, the manner of securement permits removal of at least a portion of the spiral coil as necessary or desirable for performing maintenance and/or replacement. The spiral coil sufficiently engages the inside of the tube, thereby creating at least a restriction to the passage of water between adjacent pockets contained between the thread pitch defined by the spiral coil. Ride participants are moved along with water pockets trapped between the pitch of the internal profile presented by the combination of spiral coil and tube from one end of the tube/spiral coil combination to the other end by rotation of the tube in an appropriate direction.
