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.
