Modeling the hull as a mesh

The Subdivision Surface was great to shape the hull. However, you need to use different methods to create the cabin and the cockpit. You need some sharper corners and straight edges to define the cockpit and the cabin. For this, you'll shift back to modeling the mesh object. First, you need to convert the surface to a mesh object, and then you can create the cockpit and use it to build the cabin.
