As mentioned previous, the bulkheads serve as the bones of the ship and will provide the base for the hull’s planking. The bulkheads are cut square, and therefore do not provide a solid fitting for the planks.
The bulkheads must then be sanded so that the planks have an even fitting along the bulkheads and provide a stronger, more seaworthy ship.
The ship will be “double planked”, which means a think layer of planking will provide the base of the hull. A second layer of thinner, more decorative layer will then be added.
