Did trainees sleep aboard British school ships?

Did students at British school ships sleep aboard or only attend classes there?

They initially tended to live aboard, but larger schools increasingly accommodated students ashore.

The arrangement depended on both the ship and the period. Early students commonly slept aboard the vessel that housed their school. As the institutions grew, shore facilities took over more of the accommodation. The answer therefore describes a gradual institutional change rather than one rule applying to every British school ship.
