Why Portsmouth suited a preserved HMS Victorious

If HMS Victorious had been preserved, where should she have been docked?

Probably Portsmouth, because London had limited suitable space for a carrier of her size.

The answer acknowledges the appeal of a London museum berth but notes that the Thames has limited space and that a large carrier would transform its skyline. Belfast already fits her berth and setting unusually well. A preserved Victorious would therefore make more sense at Portsmouth, where her naval context and physical scale could be accommodated.
