We'll do the planform first, laying out the 2' by 4' ply once cut in half, and adding spars to form a 'picture frame' to either side.
Those are the lateral strips parked there alongside and I thought about insetting them within the ply to make things look a little neater, and then couldn't be bothered; thus we can set them to one side for now.
When the Titanic was built the outline of its cross-sections would be chalked up on the floor at full-size in the shipyard for the workers to base the metalwork on, and so I feel we're recreating the glory days of shipbuilding here in our own tiny way.
