I saw a picture of the Queen Mary 2. Ten lifeboats on a side, 20 in all. The ship can carry 2620 passengers and 1254 crew. So 3874 into 20 is 194 people per life boat. But you need to plan for some boats being more full than others, some breakage, etc. So let's assume 10% overcapacity, or about 215 per boat. Most restaurants don't have that capacity. Do the QM2's boats? Who built them? Do the lifeboats have boats, food, electronics, storm shells?
