 The Chilean naval officer's dress uniform is navy-blue with visored hat, sword strap (for petty officers and cadets, only during parades and ceremonies), navy-blue trousers, and black boots.The enlisted uniform (for sailors and petty officers) evinces a mix of Prussian and British influences, having a sailor cap with the dress while the Marine enlisted and NCO uniform is a dark-blue polo with trousers and a belt plus a peaked cap.The dress uniform of the naval academy "Arturo Prat" is also blue with trousers, but with headdress similar to that worn by Prat and the crew of the "Esmeralda" during the Battle of Iquique in 1879.
