Naval museums for a short Portsmouth visit

Which places deserve priority during two free days in Portsmouth?

Concentrate on the naval museums, including the Historic Dockyard and sites across the water in Gosport.

Portsmouth's Historic Dockyard and naval museums provide the core of the suggested visit. Gosport offers additional sites across the water, including Number One Bastion and the Explosion Museum. Alex Churchill's Mary Rose tours are recommended, along with time with Churchill and Kate Jameson, who work together. Guided visits depend on advance booking and availability.
