Another change that was brought about by the Titanic was the requirement that ships must have enough lifeboats on EACH side of the vessel to accommodate everyone on board. When a ship is listimg hard enough to one side, the lifeboats on the other side could not be lowered. The Titanic was the first time the international distress signal “SOS” was ever used. FWIW.
I’ve long wondered why they don’t just put some wheels on the sides of the lifeboats so they can roll down the side of the ship if they need to?
titanic was NOT the first time SOS was used. the first time SOS was used was mentioned in the timeline in the article. I have a copy of IIRC the Boston paper on the titanic. there’s an article onthe back page about another ship issuing an SOS before the titanic does.
