I totally see how Lynch comes into mind. I do not know if I’m capable to deliver on that order ;)
But from the top of my mind one could chain the events in the vessel with another and intersperse several, analogous dungeon-scenes when everyone is sleeping.
But I’m afraid this would be more of a script than a ttrpg module, as it would be quite hard to make the interchanging happeings relevant to each other without building the finest railroad space has ever seen.
But I will let the idea simmer for a bit and re-visit it. Thank you :)
