Question

IF we took all the boats and ships out of the sea ,how much would the sea level drop?

Answer 1

Allthe ships would only accountfor less than1mm in sea levels,,

Answer 2

that's a very good question!

i don't know the answer but i imagine it would make a difference.

Answer 3

ES, the seas occupy so much area, about 70+% of the surface of our planet, the the difference could not be detected. It could be calculated, if you wanted to take the trouble, but the amount of drop would be insignificant.

Answer 4

it wouldn't make any measurable difference. if took all the animal and plant life out however it would drop by more than a metre

Answer 5

it wouldnt drop cause the ice caps are melting

Answer 6

i dont think there would be a dramatic change in water level since the weight of each boat or ship is displaced by the buoyancy. Moreover, due to the global warning, water level is actually increasing

Answer 7

If 50% of the oceans were covered with ships, then the sea level would drop by half the average keel depth of the ships (as the water rushed in to fill the holes) Let's say that's 80 feet for conservatism (if they were all supertankers).  So the sea level would drop 40 feet.

Of course, we know that with an average sea surface area of 335, 258,000 sq km, and a supertanker is only .026 sq km.

In other words, it would take 38, 461 supertankers to even displace 1000km...or .00029% of the oceans surface.  Since supertankers number about 4000, I'd say an extra 34,000 should cover all the other ships on the planet, being that they are smaller but more numerous.

And even then, it would take 172,413 TIMES as many ships to get to that 40 feet drop.

40 feet divided by 172,413 = .000232 feet, or .0027 inches, or about the thickness of a sheet of paper.  

In my book, not worth measuring.
