This is a fun solo or family activity. The maritime museum has has 7 plus ships to wander through and explore. They make it fun by giving you a 'passport' to stamp as you enter every ship: 2 submarines, the HMS Surprise ( think Masters and Commanders, the Star of India and the Berkeley Ferry, just to name a few. It can take as long or as short a time as you want. There is lots of information and also ship models, so you can get very involved or just wander from ship to ship.
