I am going to go against the majority and suggest you get a 6 cabin cat. The Moorings no longer bareboats their 5800’s but there are options with Dream Yacht, Voyage and perhaps some of the smaller companies. 12 on a 50 foot plus cat is not crowded. Your costs will be less and everyone can socialize. There will be plenty of room for supplies and other storage. A 52 foot cat has probably twice the living space of a 42 yet people routinely go out with 8 on the smaller cats.
