. Its carriage can provide speeds up to 20 knots. The High-Speed Basin comprises two adjoining sections: a deep water section and a shallow water section. Wavemaking capability exists in this basin, and there are three large underwater viewing windows at different elevations which are set into the wall about mid-length. The high-speed carriages can provide complex motions for the model at speeds up to 50 knots.
