You’re probably somewhat familiar with the concept of a wind tunnel being used to refine the design of an airplane. Did you know that ships have long been designed using a model basin? What’s that? Simply a very large, long pool in which scale models of the hulls are tested. The hydrodynamics of a given hull design can be tested and refined. One the the most famous model basins is the US Navy’s David W. Taylor Basin, located in Carderock, MD. Built in 1939, it replaced an earlier basin built there by David Taylor. The DTMB still serves the US Navy to this day.
