Why did everybody think that the Titanic was not sinkable?

Answer 1

The Titanic was ahead of its time for a luxury liner. It was the biggest ship to date (for its maiden journey) and a ship of that scale that floats is impervious to most storms and hurricanes. Because of its size it was built with a lock system. In other words, it was built in sections so the ship could withstand any serious damage by "locking" the section off that was damaged so the other sections would not fill up with water. The damaged section would theoretically take on water but the water would not escape this section into the other sections. On top of this system were a pump system that was in all industrial ships. Each section had its own pump system. (the pumps were used to remove water from the ship.)

An earlier answer described what happened to cause this not to work. The ice berg ripped it in a long line like a piece of paper.

The ship builders knew it could sink. Every ship is sinkable but the Titanic was truly seen as extremely unlikely to sink. This was a freak accident that happened to the ship. It was not expected or even imagined... The owners of the line and the press at that time marketed as "unsinkable."

Answer 2

Because it had thick double walls with pump chambers between them. The idea was that if the outer wall got damaged, water wood flood into the chamber and be pumped out again, so the ship wouldn't sink.

That would have worked in principle, but the iceberg slit open most of the side of the ship, so too many chambers were flooding, the pumps couldn't keep up, the ship started leaning, and more and more water got in.

Answer 3

I believe it was thought as unsinkable becuase it was a massive ship. It was made from strong material and was very powerful. If you think of all that in one, sounds like a pretty strong ship.

Answer 4

Because it was built with essentially two hulls- One inside the other, so it was thought that if the outer failed, then the inner would keep it afloat. So went the theory, at least... ;-)
