IMHO, the best way to see sites of interest for naval history is on the water. On May 2nd Dad and I sailed from the Hamble River to Port Solent Marina in Portsmouth Harbour passing about 1600 years (or more) of naval history along the way.
Let's set the geography first. Dad keeps his boat on the Hamble River in Hampshire, probably the most crowded yacht anchorage in the world as seen below. It has a long naval history and on its upper reaches lies the wreck of the Grace Dieu (Henry V's flagship) from 1418.
If you are into your naval history this is essentially ground zero. Celts, Romans, Saxons, Vikings, Normans, French, Spanish, Dutchmen and Germans have all made their presence felt and their advances mostly rejected. We sailed through the Spithead anchorage where a young Hornblower got sea sick etc, etc.

Here's how the defences look in 1914.
