A little boat like a floating papasan chair. Perfect to lay in and look at the sky. Exactly big enough for two people to snuggle. The supermodels in the boat are Arwen and Saul. This boat is part umiak, part currach, part coracle, part papasan chair. Here's how to make a tougher skin for it from truck tarp material. The book "Umiak" by Skip Snaith will fill in any construction details that aren't clear here.
The boat ended up being 9'6" long, 43" wide (measuring to the outside edges of the boat, and 18" deep in the middle (measured on the inside of the boat.)
The first step was making the stems.
I sketched them out freehand and cut them from 3/8" marine okoume plywood.
To beef up and widen the outer edge I glued on some more plywood using epoxy thickened with wood dust as seen here.
White flour works just as well, whole wheat flour doesn't. Don't use 5 minute epoxy for anything, it's not waterproof.
If I did it again I'd make the stems taller and not nearly as beefy.
