Here, demonstrated by my lovely assistant Rick, is a boat battery. A bit bigger than yours and mine eh? What if I told you that this week we were on a boat powered by 300 tons of these batteries? Yes I did check that figure, 300 tons! Then what if i told you that the boat could recharge the all the batteries from its diesel engines in two or three hours? Then what if I told you that at maximum speed the batteries would only power the boat for about half an hour, or at canal speeds, 3 or 4 knots, the batteries might last a day and a half? Have you guessed what boat this is? Answer towards the end of this post.
Here's another picture of Rick at the same site.
Can you see him? If you follow the right hand white line on the floor and enlarge the photo, he's there with his arms outstretched. This is half the floor of the upstairs part of a shed. Some shed huh? All made from timber using construction methods used in building timber ships in the early nineteenth century. Well it would be, because this is where wooden warships were built and fitted out. Downstairs is now crammed full of all sorts of old machinery including some made by the firm that Rick and I used to work for when we first met in the dark ages.
Then, on the same site, we took a look at this machine in operation.
This is in the longest brick built building in Europe, and the machine is making something nearly a quarter of a mile long. Rope. An amazing thing to watch. Here's looking down the building. We never ot to see the other end - too far away. The workers use a bike to go up and down.
They made two such lengths together in about fifteen minutes. The machinery and method are unchanged since Victorian times.
If you think all this, and a lot more, is worth seeing, take yourself down to Chatham Historic Dockyard,
where you can see how they built ships like HMS Victory, as well as 20th Century Naval ships and fitted them out. It's a vast site with beautifully kept buildings and it's a totally brilliant museum with so much to see, including HM Submarine Ocelot, which is of course where all those batteries belong. You get a full bow to stern tour of Ocelot, and if you do, you'll never again complain about lack of space on a narrowboat!
The whole site is immaculately set out and truly fascinating. (You'll gather I quite liked it!) For me, one of the special bits was to stand in the mould loft where they showed us how the shapes of the hull of Victory were laid out, but unless you don't like boats or rope, or beautiful buildings, or history, or Victorian engineering, you'll find something to enjoy.
PS. We also visited Winston Churchill's house, William Morris's house and the National Trust's most daring and expensive(and amazing) house restoration, Ightam Mote, while we were at it. Every one a gem. Four days well spent.
