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.

Step 1: Stems
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.
Step 2: Set Up the Frame
Fiddle around and change things now when it's easy.
The stem-headboard lashings are nylon string soaked with epoxy afterwards because I was confident those parts wouldn't need to change. It turns out this boat wants to turn around and go the other direction regardless of which direction it's going. So I'd make the next keel with less or no rocker. Water sometimes splashes over the bows, so I'd make the bows higher.
Put those two facts together and the stems will have to be taller too.
