I’m ashamed of the crap quality (ironically, I’ll put the vector artists’ tag on here to credit them, but I’m reluctant to put my own…), but I just wanted to throw something together real quick to reflect on something really neat…

We’ve come a long way.

“Titanic” in 2018 would need for satellite iceberg tracking and surface search radars and everything to come together and fail in an extremely unlikely way. But you know, with so many thousands of voyages doing their rounds, a 1-in-a~~1,000 thing does still sometimes happen, but the two or three times it has, nobody was even hurt, and these modern-generation “mega cruise ships” are fantastically harder to sink, still.

And yet even for the Titanic in 1912, there was a ship near enough to rescue all those who froze, but its communications equipment was off so it didn’t receive the distress call. And even then, if they’d just brought enough lifeboats, those aren’t exactly modern space-age tech.

Still though, it’s neat to reflect on all the advancements we’ve made.

There’s apparently a Titanic Replica ~~ full-scale, actually-functioning ship, perfect to form (with the exception of modern safety standards such as sufficient lifeboats, GPS tracking, modern radar and communications systems, air conditioning, and I’m willing to bet the nice little regulations such as self-lit “EXIT” signs) ship. But as the article said,

By at 40,000 tons, 840 cabins and room for 2,400 passengers and 900 crew members, passengers may feel the ship a bit smaller than the mega cruise ships of today.

Even lower-mid income people of today are used to more luxury than the tycoons of 1912. I doubt they had all this, either.

Never mind the fact that if you want to go from Europe to the US or vice-versa, you can do it in a single day on a jet-liner…

Here’s to the engineers, who change our world one year at a time, until looking back, it seems we’re almost like gods compared to the people who couldn’t instantly talk across the world, make images like this in 10 minutes, Google the knowledge to write this, and fly across the world in a single day.

This, people, is why you were taught Algebra in school, and why you should care about math and science class, because those things change the world.

Needs more Starburst

The sad fact remains that in the event of a hull breach, you would be far, far safer of The Great Eastern than any passenger ship today. Double keeled, double hulled, fifteen transverse and a longitudinal bulkhead plus several whole decks floors that were also bulkheads gave her up to sixty watertight compartments! She even had an incident where she gashed her outer hull along a length of 29.9m (85ft) x 1.52m (5ft) and all that damage did was cause a slight list to starboard. Far more severe damage than what ultimately sank Titanic half a century later and all from a ship built in the late 1850’s.

To put that into context, at that time building a ship mostly out of metal was considered cutting edge in naval architecture by itself! And she wasn’t small either, 211.2m (693ft) long with a 24.3m (80ft) beam and at 19,000 GRT in weight and with a maximum capacity of 4,000 people, there wasn’t a passenger ship that was her equal until Lusitania’s introduction in 1907 and she wasn’t overshadowed in all technical aspects until Olympic’s introduction in 1911. Yet neither were safer and in fact in Olympic’s case as well as that of her sisters, by this stage the only safety design that remained from The Great Eastern was the they had the exact same number of transverse bulkheads. But even there it wasn’t as safe, where as Titanic’s bulkheads reached at maximum, 3m (10ft) above the water line, The Great Eastern’s reached three times higher still.

The military term ‘defence in depth’ best describes The Great Eastern’s approach to defence against hull breach and nothing that has come before her, or after for that matter, has been designed as comprehensively towards safety. But even with almost none or watered down safety features, even Titanic had a few advantages over a modern cruse ship in a similar circumstance. One was that you would have a higher chance of securing a place on a lifeboat then than now. Most of the lifesaving craft capacities of a modern cruse ship resides in inflatable life rafts, in some cases, up to 70%. On a passenger ship that can say with an occupancy rating for 6,000, that might mean that only 2,000 can abandon the ship in such a way. At best, some ships can have lifeboat capacity for half of the passengers and crew. That’s exactly what Titanic had but what you won’t have that she had was the time and ability to launch all of the rescue craft.

Modern cruse ships are quite top heavy, meaning that their centre of buoyancy is far from the centre of mass. This feature means that the ship’s motions are faster, but smaller, than an ocean liner that Titanic was, whose centre of buoyancy is close to her centre of mass. This is to enhance the comfort of those on board, but leaves the ship potentially dangerously unstable in poor weather or when she’s taking on water. If she lists enough, full capsize results and it wouldn’t take much to upset the ship’s balance lance. You might find quickly that half of the rescue craft become useless due to excessive list. Shipping lines still assume that their massive ships would take many hours or even days to sink, all remaining level throughout the process, allowing for rescue ships to arrive and ferrying passengers and crew to safety. Despite being beached on the coast with ample assistance, it still took six hours to completely evacuate Costa Concordia. If she had drifted into deeper waters, the death toll would had been enormously higher that it was.

Luck still plays an enormous part in keeping people safe in the maritime passenger industry. Being consistently lucky isn’t an insurance policy, it’s a disaster waiting to happen. I could go into even more detail but I’ll leave this here for people to contemplate.
