Portsmouth Itinerary

Will be doing a day trip to Portsmouth in the summer from London. Mostly to see Victory.

Wondering if it is feasible to do both the historic dockyard:Victory, Warrior, M.33 and Mary Rose, as well as D-Day?

I've been reading this isn't a realistic or a feasible plan.... We aren't planning on looking at/reading everything. To me anything more then 4 hours in a museum is tiring so ideally we would be there 10-4 and then 3-5 at D-Day. But I'm also not interested in having to rush from one place to another either. Ideally being able to comfortably see these timing wise together.

Victory is the most important to us, the rest would just be nice to see. M.33 could just be a walk by. Warrior and Mary Rose quicker pace the normal if necessary.

I don't have a problem cutting D-day, would likely just spend more time at dockyard, grab a lunch and then visit the Southsea Castle for a bit before heading back (I'm assuming this is going to be what the plan will be now).

Thoughts?

Thanks.
