I believe the dazzle paint was designed to make it harder for enemy warships and
submarines to correctly judge the range by making it harder to determine the actual
size of the vessel.
I read in interesting book a few years back, about a sailor delivering supplies to the Russians during WWII. He said that the black and white pattern was so German U-boats would have trouble finding the range/size/heading of the ship.
*Edit, just noticed it's all been mentioned before, shucks
