This is probably the MK10 design of our shelters and, as ever, each time we put one up we learn a bit more and simplify. I can't take all of the credit on this one though - the design is based on an idea by Jasper (my eldest son) to hang the parachutes from a central 'mast' and to tension it with a large metal ring (or two as it turned out).
I'm pleased to say it's been a great success: it stays dry and taught in the rain and just gently sways in the wind (despite being held down at three opposing points).
The whole structure took just one day to erect with Adam's invaluable help, together with a quad bike and pulleys to do the hoisting. If I'm honest I can't really call this one work - just adult den building I guess!
