Getting Square

Today we marked the internal ribs for length; the fronts were locked, and we used the jig to determine the lengths.  That done,  the next step was to square up the sides.  After clamping / shimming the main yoke into place, we added temporary firring strips to the front edge of the doors in order to square the sides to the platform.

That accomplished, and with the onset of a torrential downpour, we clamped a temporary shelf onto the fore starboard, which represented high ground.

What else was there to do but wait out the rain?
