Design flaw

The project had one large design flaw, the big rear door, in particular the inability to close it whilst in the rear cabin.
So if you are, for instance, by the sea and it gets windy, you can't close the door and hunker inside. You would have to get into the front cabin.
In addition, the big rear door was a bit bigger than I first planned and a lot heavier.
After a great deal of thought the only solution seemed to be to hinge part of the door so that it could fold down and attach to the supporting doors for strength but also allow us to get in and out.

So off the came to door again. A bit of cutting here, a bit of welding there, a few hinges extra and it was ready for a trial fit.

 Of course now that I have put in a hinge I also need a way to hold the door straight as well.
All up the door weighs 20kg. This puts a lot of pressure on the supports. It all looks ugly.

Version 3 will do without the second part of the door all together. This reduces the sheltered part at the rear but more than halves the weight of the rear door making it much easier to support and manhandle. We will have an 'awning' made to create a covered an enclosed rear. The size and details are yet to be decided.

I have spent far too many hours constructing, deconstructing and reconstructing this door and I am heartily sick of it.
