Stitching the Amas

Now that our plywood sheets are scarfed, they are ready to be laid out and cut into the ama panels. Each ama has two bottom panels and two side panels. Simple enough.

In the photos below, the panels are laid out from the plans and a batten is used to spring a fair line.

A jig saw is used to cut the panels out and then a block plane is used to smooth and fair the cut. Here are the finished panels ready to be stitched up.

The bottom panels are laid one on top of the other and stitched along the bottom every 4” or so using 18 gauge copper wire.

After the bottom panels are “unfolded”, the transom and bulkheads are stitched into place.

The side panels are then stitched to the bottom panels, transoms and bulkheads. At this point, you can see the amas really start to come together and take shape. There is an instant gratification component to stitch-and-glue boatbuilding. In less than a day, we went from panels to amas.

In our next post, we begin the process of filletting and fiberglassing the joints and turning what is now a tentative shape into a permanent hull form.
