The object is said to be “buoyant” when it floats due to low density. By spreading out the concrete used to make the boat over a larger volume, the apparent density of the boat becomes less than that of water. Hence the boat floats!

Shipbuilders of the early years of shipping would use a copper coating as a biocide, to prevent organotins from sticking on the vessel’s hull. That copper coating was responsible for the ship’s red color. In the 21st century, it is more than obvious that antifouling coatings can be mixed with any color.
