High Speed Towing Tank

The high speed towing tank is a straight tank 313 feet long and 12 feet wide and can support water depths as high as 6 feet. It is one of the highest speed towing tanks in the world with a monorail supported, cable driven carriage capable of speeds from 0 to 100 feet per second with speed control of .01 feet per second.

The high speed tank can produce a wide variety of wave types through an articulated double-flap programmable wave maker. This wave maker generates both regular waves and pseudorandom waves and can be programmed to produce nontraditional wave forms such as wave pulses, complex periodic waves and dual and triple wave trains. The wave maker can be used to generate both regular and irregular waves with heights up to 20 inches.

Shallow water and shoaling conditions can be duplicated with the installation of  "false" bottoms. Plunging surf can be produced on a 40 foot surf beach. Computer programs adjacent to the tank facilities provide menu-driven selection of the following types of wave spectra:

• ITTC, ISSC, Pierson-Moskowitz, Bretschneider
• JONSWAP
• Neumann
• Noznesenski-Netsvetayez (Russian)
