Eastern Arctic Kayak Construction - Ribs

Back to working on the EA kayak after more than a month's hiatus.
Today I tried notching and bending a stick for ribs, but there was so little wood connecting the segments that I gave up and decided to just do the ribs in three parts.  At the same time, I started refinishing an old wood and canvas canoe so I didn't finish the ribs but got far enough to work out how it will be.
Pictures follow.

View from the bow.  Set sides of the ribs are sitting in their mortises, ready to be trimmed to proper length.  On the ground, just to the left of the EA is a stitch and glue surf ski that somebody dropped there.  Don't know who.  I will have to call some of my friends to find out who it was.  Soon as I get caught up on building, I will go and try out that surf ski.

The first completed rib.  I just nailed the center section to the sides with bronze ring nails.  Seems to work.  The joint will be backed up with some stringers. Note the battens clamped to the sides of the rib sides to mark them for where they will be trimmed.

Side view of the stringer the top of which marks the elevation at which the rib sides will be trimmed.  Ribs are roughly 5/8 by 1/2 inches.

The view from inside in the direction of the stern.  Those ropes look so nautical.

Another shot down the center of the kayak. The first completed rib is visible.  Tomorrow, I trim the rest and cut and nail the remaining center sections in place.

And the ribs near the bow.  With any luck, this frame will be completed soon.
