I've added the external stems and shaped them into satisfying curves, and filled in the fiddly gap where the gunnel meets the stem. Both hulls now have a base panel, with nice rounded edges and nails punched so they're no longer proud of the surface.
Seats and supports at the blunt end of each hull.
Starting work on the Ama. There are eight long strips of ply and eight chine strips - this would go faster if I had more clamps and more space, or if it was warmer and the epoxy took less than 24 hours to set.
