If you took all of the boats in the world out of the water how much would the water level drop?

Question

I would like to know the drop in water lever if every boat in the world was lifted out of the water at the same time.

Answer 1

I doubt any but if there was a drop, it would hardly be noticable or measurable...the world is 70% water and it hasn't risen much over the centuries with everything we have put in.

Answer 2

probably not at all. maybe an inch or so. because the water is constantly moving it would even out very quickly. you wouldnt notice any drop in water level because the amount of boats is only a fraction of how much water there is in the oeans

Answer 3

Considering this. The rivers of the world constantly replace much more water than ships displace, without any noticeable rise in sea level. I t is reasonable that the water would not drop.

Answer 4

Mathematically, it could be figured out but first you need to know the displacement (tons of water displaced) of every boat in the world and how many total (tons of water) exist in all the oceans in the world.  I don't believe any references exist in either category to mathematically figure it out, but I can say this with some certainty......to the eye you wouldn't know the difference.

Answer 5

If you had a controlled environment so that there would be no surface evaporation, no streams, rivers or rain feeding the body of water, no tidal action and the total volume of water is constant, the water level would drop by an amount equivalent to the total displacement of all the boats/ships removed from the water. How much in inches/centimeters depends on the total surface area of the body of water.  In the real world of coarse it would be so small as to be immeasurable even if you could control all of the factors.
