Ship Speed: Why are Massive Ships So Painfully Slow?

Water transportation has always been an important way for people and goods to move around the world. According to surviving clay tablets and containers, waterborne vessels were used as early as 4000 BCE.
Ship engineering design has come a long way since then. Ships have become more sturdy and their size increased dramatically. However, even though their size and design have changed over the course of time, their speed stayed relatively the same. Whether it is a cargo ship or a cruise ship, these engineering marvels tend to be on the slower side.
Compared to the other types of travel, ships take quite some time to get to the destination. If you were to go from NYC to London by plane, it would take you seven hours. Traveling by ship, however, would take seven days.
This comparison may sound normal and you might have already known that big ships are very slow. Still, questions like “Why are ships slow?" or "Can ships be faster?” can keep your mind busy. To give you a headstart: Yes, ships can go faster, but they usually tend not to. There are several reasons for that but in general, slow ships are good both for the environment and economy.
Ships have been around for a long time and engineers have tried their best to improve them. Their design and security have improved but their speed has stayed the same. The reason is not that we can not make ships go faster but because we choose not to.

Slower speed has nothing to do with less CO2 emissions... One can push more air to the engine to travel faster and that will actually reduce emissions as the fuel burns better... In diesel engines, preheating is more important factor in efficiency. Even though aluminium is used in some engines to reduce weight, the critical parts still need to be steel as aluminium has too low melting point. When you travel slower, water resistance and wind resistance are lower, so increasing speed to double means power output of the engine needs to increase by more than factor of 2. Increasing speed also changes draft of the ship as more water is pushed under the ship. Change of draft can also change stability of the ship as there is more surface to attract forces of wind.

Great production and info. 👏👏

Hi, Hope you are doing well. May I have permission to use one of your videos for a Driving School Curriculum? for beginner/student drivers. Thank you

Visual 8/10 Content -∞ (Totally gabage) Lol And actually these massive ships' hull speed is really fast, much faster than small ships due to their longer length and special design. Speedy boats are very light and can be pushed to kinda bounce on waves (way faster than hump speed) so they are exceptional

[@jamestaylor4324]

The funny thing is that ships today are slow unlike titanic and other ships back then went for speed

[@mowuvz3672]

The content is total garbage. For every hull design, there is a max hull speed where water wave in front of the bow is so much that adding more power to engine won't speed up the ship anymore. This is true for all displacement ships. Planning boats like speedboats which can ride over water surface can go much faster but that's only feasible for smaller boats.

First view

[@robbymarton74]

Um because there’s a lot of shit on them? Fffff wast my time

[@pisnotmynamesisnotmygame3757]

380 tons of fuel equals 1000tons of co2?

[@jashansandhu8653]

Fuel doesn't burn alone it requires O2 in the process and that too ends up in the end product
