Go to Greenwich to pick your three ships and you'll be spoilt for choice. They are everywhere. You can choose those with names. Go for the Cutty Sark tourist option.
Admire Yinka Shonibare's Nelson's Ship in a Bottle.
Or walk through Turner and the Sea to see his interpretation of the Victory and the mayhem of Trafalgar - why did I not realise that the sails would be torn to shreds by fire and cannon? Or the spectacle of the nation's favourite Fighting Temeraire being towed up river, with a degree of artistic licence. Then make your way to the last couple of rooms and be blown away in a breathtaking mini-storm by the little colour sketches with their merest suggestions of ships.
I may even have been at all at sea when I saw them.
