Pic 18: More secondary (tertiary?) planking. These mahogany strips - technically called 'wales' - must be placed exactly right, because they control the placement of the cannon ports. In places, to achieve this they needed to be curved in the flat plane, which meant cutting that section into several parallel strips prior to gluing. I delayed fitting the prow because I thought it would be easier to fit the planks without it. I then carefully cut a parallel channel down the front to take the prow later.
Note: Be careful when sanding light and dark woods in close proximity. The sandpaper can pick up dust from the dark wood and impregnate it into the grain of the light wood.
