HMS Victory,

which is undergoing a major programme of conservation at the moment with the new support rams in place and much of the outer hull planking removed to facilitate deeper rapairs before it is replaced with new planking,

and HMS M33,

I also spent some time in the boatyard hall were they do traditional boat building and repairs on heritage small craft. Very interesting talking to some of the volunteers who donate their skills and time and good to see women/young people there as a positive for the future.

I still have lots to see on a future visit, HMS Warrior and the submarine museum, for example.
If you're down Portsmouth way I recommend visiting, and if you're not sure about how to entertain you're better half, Gunwharf Quays shopping outet is less than 5mins walk from the Dockyard - easiest way to get there is the train to Portsmouth Harbour station, which is equidistant between the Dockyard gate and the entrance to Gunwharf.
