At least 45 passengers
Depends on the size and seating capacity of the lifeboat. And there's also a limit as to how much weight a lifeboat can hold
2 in numbers or 10% of lifeboat capacity.
The reason to know that capacity of a lifeboat is that if you should happen to be in a sinking ship and the lifeboats are being boarded, you will be able to tell when a particular lifeboat is full, and if it is, rather than trying to board it, you will look for a different lifeboat. If lifeboats are overloaded, then they too will be unsafe and may also sink, which defeats the purpose.
Titanic did not have enough boats for everyone. Although she actually provided more lifeboat accommodation than was legally required, the disparity between her capacity and lifeboat capacity was 2.369.
Shortly after, there was a change in required lifeboat capacity.
There was not enough lifeboat capacity for everyone to be saved.
Hardin uses the metaphor of a "Lifeboat" to illustrate his argument about overpopulation and limited resources. He portrays Earth as a limited lifeboat with a finite carrying capacity, and argues that allowing unlimited reproduction will lead to the sinking of the lifeboat for everyone.
If every lifeboat was filled to capacity and everyone in the survived then 1,178 people would have been saved.
The Titanic carried 20 lifeboats with a total seating capacity of 1,178 people
For each person in the lifeboat: food - 0,5kg and water - 3kg.
If you are referring to the Titanic's Lifeboat 13, there were 54 aboard. The capacity was 65. There were at least 14 male passengers aboard. Source: http://www.icyousee.org/titanic.html
