WHY DON'T CRUISE SHIPS TIP OVER? | An introduction to ship stability

What keeps ships from toppling over? I explain how Cruise ships stay upright and what can cause them to lean over.

This video introduces the concept of the centre of gravity and the centre of buoyancy with reference to ships. I show how they work together to keep ships from falling over.

I am a retired UK Class 1 Master Mariner and I like this video. It's not meant for mariners as a teaching aid. It's meant for ordinary people and it uses non specialist language. Great stuff and I am going to recommend it to my MSc Maritime Studies class in Singapore. Some of them are mariners. Most of them are not and this video will be ideal learning for them. Well done sir!!

I love how you just shifted the centre of gravity of a cruise ship with a 10kg weight

On a recent Cruise in the North Atlantic in winter I thought it was going to go over. The only person who thought we were safe was the captain who just laughed and said "Disney's rides only give you this for a couple of minutes I have given you a whole week"

Sweden's most popular tourist attraction is the warship Vasa, built in 1628. Unfortunately the constructors had not watched your video.

Because if they did no one would ride them

The fundamental idea is: The center of buoyancy for an object is the center of mass for the fluid it displaces.

Hey Casual Navigator ! I'm deeply afraid of ships and the ocean and with your videos now in June 2020 I am learning about my fear and how irrational it is because your videos explain how ships work and now that I understand that Im not as afraid to board a boat

On a topic of such gravity as ships capsizing, you kept the mood...



...buoyant.

The quality of this video tutorial has been recognised by many of its viewers, but one aspect has not been commented on so far: there is no 'music' track added behind the speaker. I am so happy about that because many other YT videos have intrusive, and very often highly repetitive, 'musical' phrases added; they distract and irritate me enormously. So well done and thanks.

That's why swimming pool on cruise ship always on the middle doesn't matter it's on aft or fwd deck, never on the sides, because water is heavy and it also add center of gravity for the ship.

Love your channel. Precisely explained, easy to understand, and no unnecessary/annoying music, sound, voice or topics. Well done 👏 : )

We were just taught in school that ships don’t sink because they’re less dense than water, we never learnt all this extra stuff

[ianpatterson]

I'm afraid that this landlubber still can't grasp the concept of buoyancy, BUT I must say that was probably the best educational video I've ever seen. You have a lovely voice sir, you take sensible pauses, and you're perfectly in sync with your excellent diagrams! Thank you. :-)

[МихайлоСєльський]

Wow, these 10 kilos were so intense))

[michaelbuntine]

I actually wish you was my teacher when I was in school.... I just learned so much from you... And I understood the lot...and it's so interesting.. THANK YOU 👌👌

[arnoldkokonya]

Am a software engineer. I don't know a lot about ships but this video explained so much step by step, that I was able to understand a lot about ships. Wow. Just amazing.

2:11 That ship Design looks like a Sippy cup

The boat in the intro is the Queen Mary 2 from the Cunard line and is not a cruise ship. It's an ocean liner (The only one left) like the titanic. It has a a deeper hull to help stabilise during Atlantic crossings.

Thanks. I’m completely unschooled in such matters, and I’m finding these videos really interesting and helpful.
