Abstract: A lightweight, portable artificial sport log for logrolling, having physical properties that mimic a selected natural log, has a hollow cylindrical shell of a suitable high density polymeric material and an internal baffle support shape of a rigid polymeric material fixed to the internal surface of the cylindrical shell. One or more sealable fill/drain ports allow addition and draining of water from the artificial log. Auxiliary training devices to control log rotation are disclosed, as is an inflatable embodiment.

Abstract: A lightweight, portable artificial sport log having physical properties that mimic a selected natural log is disclosed that has a hollow cylindrical shell of a suitable polymeric material defining a volume having the desired dimensions of length and diameter of a selected natural log of interest, an internal baffle support shape of a rigid polymeric foam material is fixed to said internal surface of said cylindrical shell, end closure members at ends of said hollow cylindrical shell provided with sealable fill/discharge openings for adding and draining water from the artificial log. The internal baffle volume and shape are determined such that the buoyancy of the artificial log generally equals the buoyancy of the natural log of interest and the mass moment of inertia resembles that of the natural log of interest when the artificial log is filled with water.

Abstract: The preferred embodiment of the invention is a safe birling amusement for use in swimming pools, in which a rotating central cylinder is flanked longitudinally by two stationary approach cylinders with flattened tops; pipes extending through the centers of all three cylinders support the structure, and these support pipes are set in adjustable brackets in two facing vertical walls of the pool. All three cylinders are covered with soft foam, and a foam guard is placed over the bracket and poolside surface; thus approach to the birling cylinder is easy and safe. As well, the rotational speed of the birling cylinder is decreased by virtue of paddle-wheels within that contact the pool water; this allows users to balance more easily.
