Why Cruise Ships Are So Slow

Ships come in all shapes and sizes. From motorized dinghies to yachts; from glorious looking white cruise ships to bulky container ships and tankers. But they all share one quality: their engines seem excessively powerful, yet they still can’t seem to output the speed you would’ve expected from this kind of power.

The reality is the exact opposite of the expectations: a big liner can cross the Atlantic Ocean in a week, but a cargo ship would have to spend more than two weeks to do the same thing. For a plane to go from an airport in Western Europe to New York, for example, it would take only 8 hours. So why do we even use ships if planes are so much faster?

SUMMARY:
- You won’t be able to carry thousands of tons of weight by plane. The same goes for the number of passengers – some ships can carry more than 5,000 passengers in one go!
- So in general, ships are going slow just because they don’t need to go faster; their aim is set somewhere else completely. They sacrifice speed for better carrying capacity.
- The engines of big ships are huge powerhouses taking up entire rooms and swallowing tons of fuel each day like it’s a snack.
- When a plane flies, it needs to maintain enough speed to stay up in the air, and it needs to avoid clouds when possible.
- Unfortunately, ships have no choice but to deal with the dense environment that often almost fully covers the ship’s hull.
- Even something as fast as a bullet would slow down and finally stop after just 100ft through the water. This is why every ship needs more power to move at all.
- A large ship is naturally submerged in the water with a part of its hull up to the waterline. If the ship is loaded with cargo, it’ll be submerged deeper than that.
- All modern-day ships have a so-called bulbous bow – the thing that’s submerged in the water right under the nose of the ship.
- This is why modern ships don’t produce waves around them anymore, and their speed is no longer so heavily affected by them.
- WP-18 Special Forces Interceptor is a boat you’d expect to see in a sci-fi movie. But it’s real, and it’s literally cutting edge design is specially developed to cut through waves at the extremely high speed of 65 knots, or 74 mph.
- A rush for top speeds was, and always will be, in people’s minds no matter what. This gave birth to another incredible vessel – The Mystic Powerboats C5000.
- The max speed achieved in this boat is mind-blowing 250 mph.
- If you want to go even faster, I have bad news for you: the sea won’t let you, because it won’t be calm enough.
- So it seems like about 300 mph is the natural speed limit of the sea itself.

Do you prefer to travel by car, plane, boat, or train?

3:21 "Planes . . . need to avoid clouds, when possible." Wow! I flew as a professional pilot - military, airline, and civilian contractor - for well over 40 years, and nobody ever mentioned that. And it is amazing that in 29, 000 hours of piloting I never noticed a plane shaking from colliding with water vapor. The things we can learn from watching YouTube !
Actually what Bright Side, and their viewers, should know is that the turbulence sometimes associated with certain cloud types is about differing temperatures and resulting vertical air movement. There is water vapor in the atmosphere whether it is visible as clouds or not. That, too, is about temperature, not density.

Simple: because they're big, heavy, carry lots of weight, and drag through the water.

[kidney]

Hmmmm. I always asked myself about this thing. The fact is that it is not really that slow...

YouTube: why cruises are so slow
Cruise ship: am I a joke to you?

simple answer: bcuz they're literally like a floating city!

Why does every upload everytime I'm busy I just wanna try and be early:C

Thanks, very useful info, learned a lot about ships.

Well I did learn something new. I thought the thingy in the front was for balancing the boat AND I'm so happy my hubby is not a speed boat driver !! I need him alive ;) Thanks 👍

Hi Bright Side! Love your vids! Please can you do a video about ferries?

[carlosmorales-zyov]

displacing water uses up a lot of friction Remember water is strong

[jasperp.]

Ocean Liner Queen Mary 2 has a jet engine at the top that transfer the power to the propeller's engine below to make the ship go at 65-70 kilometers per hour.
Its still slow, but thats fast for a big ship.

I was playing a cruise ship game and found it in my notifications
