ELI5: Why are almost all boats white?

There are so many colors of cars and planes, just figured boats would follow in their footsteps. 

Edit: Thanks for the feedback!

Ever notice that the line on the side of the road is white while it is yellow down the middle? That is because in fog it is vital to see the edge of the road. White shows up better in fog. White boats don't hit each other as much in fog, then.
