This report describes the methods used to measure and describe the Phoenix underwater vehicle model. This included measurements for mass, length, center of gravity, buoyant force, radius of gyration, and moment of inertia. The radius of gyration and moment of inertia values were calculated based on the period of oscillation found from bifilar swinging the model. An uncertainty analysis of the results is also presented here. The method and apparatus described in this report proved to be accurate to within ±2mm and could be repeated for other underwater vehicles in the future.
