NotesSackville's engine-maintenance crane ran along a transverse beam through the machinery space. Sailors working aboard were expected to duck beneath it. Opening the compartment to visitors required more clearance, so part of the beam was cut away. The alteration lets children and other visitors enter and see the engine, at the cost of changing an original fitting.
