The primary use of the ballast tank is for studying ship stability using models up to 20 ft in length (6 m). Standard inclining and longitudinal trim experiments are conducted as well as large-angle roll tests for experimentally determining righting arm curves for both intact and damaged conditions. This tank also serves as an undisturbed body of water for calibrating wave gages and testing out underwater vehicles.
