This video will give you a feel for what goes on in a model basin. Basically, what they are doing is testing a smaller version of a proposed design to see how it will fare under a range of conditions. The more they can discover and correct now, the more successful and reliable the full-sized version will be when it is put into use. This scale model testing is brought to you by William Froude, scale model testing pioneer.
A model basin is a structure designed for the testing of scale model vessels. The tanks in a model basin can be used to test a scale model of the design of anything that is impacted by the principles of hydrodynamics before that object is built in full scale. Because of the Law of Similitude introduced by William Froude in the late 1880’s, we know that a model of a ship form can be tested under a variety of conditions and the results of those tests will accurately predict the performance of a full sized vessel of the same design. This testing allows the design to be perfected before construction of a full sized vessel is undertaken. Wait! There’s more!
