Designing the hull is one task, but since a vessel usually needs to be hauled during its usable life (hull cleaning, inspection, systems upgrades, battle damage), the designers other big task is to specify the cradle needed for a dry-dock. I find it interesting that the cradle builders are using flexible steel tape rulers to measure the block positions, so perhaps the tolerance of the blocks is +/- 1/8"?
