Can a color pro­tect a ship’s hull?

iD magazine - - Smarter In 60 Seconds... -

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.
