Cabin doors? That was one of my first thoughts, as well. There is a door to the head area, useless. The door sticks, very cheaply made. There is sliding wood to the shelf storage pockets above the berths. The sliding wood? Cheap, does not work very well.. I got thinking, take the sliders out, install netting.
The whole starboard berth is useless space, I sail alone. But I do not want to rip the boat apart either. The galley is a joke. With so little space, making a little change is a big undertaking. The ceiling/overhead of the main cabin is a liner. I've thought of attachments but the liner is weak.
Taking doors out ?? Good start..
