The additional search provided more confirmation on the headroom and the mention of "plan settees", but no detailed diagrams or descriptions of the typical layout (V-berth, galley location, head). I will still be able to write the section, acknowledging the limited specific details but using the available information.
Confidence Score: 4/5 - I have enough to complete the article, but the interior layout details are still a bit sparse, which I will reflect in the writing.
Proceeding with article generation.
