What's this then?

I seem to have posted every day now for over a week, so now feel honour bound to keep it up. Not really having any news today, I thought I might just post a pretty picture, but then I found these. This is the boat I mentioned in a post ages ago - too long ago to go trawling through the archive to find a link - in which I was wondering about its provenance, and, indeed, its construction. I did in fact write a rather rambling post about it late one night after returning from the Birkbeck bar, but - and this is the only time I have done this - immediately deleted it for fear of displaying too much ignorance. But there's no getting away from it; if you want to learn, you have to take that risk sometime. So, what can I tell from looking at this boat? Am I right in thinking that it's wooden? Does that automatically mean it's old? Does that in turn mean that it's been shortened? And what else can I tell from its construction, its shape?
