In the pile of model boats to be built is a 1/12th scale kit for a modern, small fishing vessel. Because of this, I've taken loads of pictures showing the back of these boats and no two seem to be the same.
I'm assuming the basic mechanics of the operating bits work the same way, but the structures found vary so much. Some look a lot stronger than others, but I can't imagine the weight of catch varies that much on boats of similar size.
Looking at these boats makes me more impressed when I have fish'n'chips. There's no way I'd want to be a long way out at sea in inclement weather on something so small!
