If you are going to be primarily sailing I do not feel that head-room will be a huge issue. If you are going to be primarily in port it might be. Think about what activities you'll be doing and how often full head room would be necessary. One can certainly cook with one's head tilted. For comparison purposes evaluate how often you are actually upright while in your home. Objects that protrude into the given head-room would be more of an issue (how many times can you bang your head into the same damn thing? Wear a baseball cap for evaluating this phenomona-you'll be amazed at what you'll run into.)
As far these things being published-if she's got a face like a madonna and a butt like a barge, how would you sell her?
