Here is a quick sheeting of the hull. The red circle shows an area where you are not meeting the two orthographic sketches.
The flatten quilt untwists the side just fine. The side triangle worked easily enough, and so did the bottom that is bent to the nose.
Use sketch references to make sure corners remain coincident from one sketch to the next. If you cannot use references, use relations. If you cannot use relations, use surface intersections to create geometry.
