WCS, a boat/ship is usually taken on sea trials after launching. Typically these trials would occur after construction, but before handing over to the first owner, or following a refit or major modification to the vessel. Such trials will establish whether the performance of the vessel meets the contractual requirements in terms of speed and handling. HMS Daring was expected to do about 28/9knots. She's done 30knots on ONE engine so far!!
