The boat starts to look a lot more complete when you start to put the decking on! The cabin now has a roof, and sides and it IS possible to sit up (ish) inside. :). There is certainly room enough to lay!
Working on the cabin now and wondering if the boat mightn't be better off without it. Still, if it's pouring rain, two people could conceivably shimmy their way in and get out of the rain.
