Would it be sensible to beach a captured or interned warship to prevent its crew from scuttling it?
Short answerIt is an option, but removing the original crew and placing guards or a prize crew aboard is usually the more direct safeguard.
NotesBeaching is one possible precaution rather than the default. The captor first needs to decide whether the original crew remains aboard and still has access to machinery or flooding controls. Removing that crew, posting a guard, and placing a prize crew aboard can secure the ship without deliberately grounding it. Beaching becomes useful only when those measures are insufficient or the local circumstances make a floating guard impractical.
