The world's oceans contain approximately 1.37 bn cubic km of water. The volume of displacement of the entire world's boats & ships is negligible by comparison. Therefore there would be no perceptible change.

We all know that water expands when it freezes, and that icebergs are something like 80% submerged.....So, if all the icebergs melted, surely sea levels would fall, rather than rise....?.........Cheers....mick.
However a very large amount of the world's ice is on land. The ice contained within the Greenland Ice Sheet represents a sea-level rise equivalent of over 7 metres. The ice contained within the Antarctic Ice-sheet represents over 60 metres of sea-level change. Therefore, if both the Antarctic Ice-Sheet and the Greenland Ice-Sheet were to melt, sea-levels would rise by over 67 metres.
This would be, generally speaking, a Bad Thing.

However this does not take into account any effects due to climate change resulting in the more volatile nature of water (which constantly evaporates and falls as rainfall, unlike ice).
