Catelyn If you don't like them you don't have to use them, but do note that this is a guide for combat ships. Plus, I could not ever make a guide for designing "good looking ships" because everyone has their own preference. for example, I think some of my newer painted walls look nice, but someone else might not even look at the paint and just yell at me for it being a wall.
You can't please everyone, I think I have found a good balance between looks and usability, but many others don't think so. Cosmoteer was built to be a combat game, not a game focused on looks. But the fact that we can make our ships look nice is a great gift, and I am not scolding anyone who does.
