You might need to expand on this bit. What makes it less pleasant? Is it an inevitability? Is there a corresponding increase in the pleasantness of the other ship? If not why not?
What makes it less pleasant is the lack of facilities to accommodate all the people that want to jump ship. If we were talking about a ship we would be talking about toilet facilities, food supplies, accommodation etc.
In Britain we may be talking about housing, employment, school places, health care facilities.
Does this movement make the less pleasant ship more pleasant? Possibly - if the people that left that ship were not contributing to the benefit of those aboard that ship.
Conversely of course, if they were valued contributors on that ship, their loss would have a negative impact on that ship and if they carried skills and knowledge on to the more pleasant ship the disadvantage of increased crowding may be well compensated by the knowledge and skills gained.
