Hi Rachel, I would be leery of using dry ice before getting answers to the question:
Is carbon dioxide lighter or heavier than air? If it is heavier, then your hull can fill up with carbon dioxide, displacing the air you need to breathe when you lay down on your berth................... Not a nice thought! You need oxygen, not carbon dioxide to stay alive. If it is lighter, then it will dissipate and no harm can be done.
