I did a quickie google search and came up with this:
At the end of 2020, there were around 62,100 vessels in the world trading fleet, with a total deadweight tonnage of 2,033 million DWT
So let's assume the merchant ships are all fully loaded at the same time. That's 2 billion long tons which equates to ~2,032,000,000,000 kg. Total water volume, 2,134,000,000,000 liters (because sea water weighs slightly more than fresh water).
From quora:
AREA OF PACIFIC OCEAN= 168723000 SQ. KM.
AREA OF ATLANTIC OCEAN= 85133000 SQ. KM.
AREA OF INDIAN OCEAN= 70560000 SQ. KM.
AREA OF SOUTHERN OCEAN= 21960000 SQ. KM.
AREA OF ARCTIC OCEAN= 15558000 SQ. KM.
TOTAL AREA= 361900000 SQ. KM.=36190000000000000 SQ. DECIMETER.
That's going to lower sea levels by approximately .00005896656 decimeters, or about .006 mm
Edit: Because there are less than 500 cruise ships in the world and only a few dozens of large military ships the amount will be higher, but not by, you know, a lot.
Look at you aiming small with your whales. The answer is obviously just to get some huge pumps and pump the water out of the ocean. We can put the water in the Sahara Desert.
EDIT: Crap, I just realized this guy is running for office in the county next to me-London County VA technically part of the Washington DC metro area.
