Use in Naval Engineering (or Naval Architecture)
Nabla is used in naval engineering (ship design) to designate the volume displacement of a ship or any other waterborne vessel. Where its counterpart, the Greek delta, is used to designate weight displacement (the total weight of water displaced by the ship), the nabla is used to designate volume displacement, or the total volume of water displaced by the ship in units of length cubed.
