Were the lifeboats filled completely or they had space to save more passengers ?
Sir J Burdette and Yourj I would like to know you that according to the designer Mr. Thomas Andrews, the life boats had a capacity to carry at least 65 passengers in one life boat, but it had a capacity and it would not buckle when lowered with 60 or 65 passengers. i exactly don't know but when Mr. Andrews came to know that life boats are carrying only 20 to 25 passengers he told to the officer to fill more passengers but it was to late because many life boats were gone. if the life boats had filled full with passengers i think the number deaths would been very less.
In my e-book, I pointed out that the supposed capacity of the boats was highly imaginative. Book I gave the first and only analysis of the boats according to current SOLAS rules. I make it plain that the large boats could only hold 65 passengers by using unseamanlike cramming. The two emergency boats were even worse. These supposedly could hold 40. Go to a handy yacht club and have a look at a good size trailer sailer. Now imagine 40 people on board and you'll see the absurdity of the rules. Those loading boats didn't do such a bad job when the realities are considered. The main thing they did wrong was leaving the collapsibles till last. A party should have been assigned to get them ready very early on. Anyone could see they would be hard to prepare and lower.
The real damage was done on shore, long before Titanic sailed, especially by Sir Alfred Chalmers. Never heard of him. Read and learn!
