Destroyer trial reports preserve collisions as well as performance

What is the most extraordinary warship trial report found in the archive?

A young destroyer captain struck a target buoy with a new ship during trials; another destroyer reversed back into the dock while attempting an early crash stop.

The first destroyer was repaired and went on to serve, so the collision became part of the vessel's trial history rather than its end. The examples show that a maneuvering program tests the officer and crew as well as the machinery, and that ambitious destroyer handling could turn a planned evolution into an immediate repair job.
