WhaT are these boats?

[englisharcher]

While out walking I saw these three boats in a farm yard.

Now I know they are narrow boats, but they look like they are for different purposes, what would they be used for?

Sorry for the bad picture, but that's as close as I could get.

I think they're all narrowboats but the one on the left hasn't had the windows made yet.

Traditional looking narrow boats to be honest.
