Can a color protect a ship’s hull?
Not only must icebreakers break through layers of ice several yards thick— they must then push the resulting debris to the side out of their way. The shape of a ship’s hull is crucial for this. Most icebreakers have a flat spoon-shaped bow. In addition the hull is coated with a 2- to 3-mm-thick layer of colored epoxy resin. Thanks to the coating’s elastic structure the bow’s armor is highly resistant. A special stainless steel layer provides additional protection by minimizing the friction between the ice and the sides of the ship.
