Sailors aboard the escort carrier USS Petrof Bay (CVE-80) take part in the time-honored 'Crossing the Line' ceremony as the ship crosses the equator during World War II. First-time crossers, known as 'pollywogs,' endured good-natured hazing at the hands of veteran 'shellbacks' -- a tradition that boosted morale and forged camaraderie amid the long stretches of Pacific war service.
