This area really is all about warships. Not only are there three WWII gun-ships moored close by (all are heading for the Dunkirk 70th anniversary next month) but if you look across the water to Portsmouth, you see HMS Warrior in the historic dockyard and a bevy of today's Navy ships, all grey metal and mysterious white domes.
Back in our floating home there was a sudden emergency on our pontoon. A yacht was just arriving, and the woman stepping off it fell badly, hurting her ankle and banging her head and face. We rallied around, picked her up and helped her on board, and suggested her husband call the marina staff who had a paramedic on hand. Luckily it turned out she didn't need hospital treatment but was quite wobbly and shocked.
