Towing tank

The towing tank at Centrale Nantes is 140 m-long, 5 m-wide, with a constant depth of 3 m. It is equipped with a towing carriage able to go in both directions, at speeds up to 8 m/s. At one end of the tank, a wave maker generates waves with heights up to 0.5 m. At the other end, waves break on a beach, therefore limiting the reflection of waves in the tank.

It is the second largest towing tank in France, the largest in a higher education institution.
