Testing of the XR-3 Captured Air Bubble Testcraft was accomplished to determine the center of gravity location which results in the minimum thrust required for a given velocity. The optimum center of gravity was determined to be one hundred and nineteen inches forward of the stern transom for velocities higher than twelve knots.
