(April 3, 2015) A ship hull model attached to a high-speed sled moves through waves at the David Taylor Model Basin at Naval Surface Warfare Center, Carderock, during Office of Naval Research -sponsored research. The research studies the fundamental physics of the water-impact of high-speed planing hulls and to measure the slamming loads and resulting motions of the craft upon re-entry into the water.
