Hello; With a maximum depth of about 7,434 meters (24,390 ft) and temperatures between -2-10 °C (25-50 °F), the Southern Ocean is known for its tough weather conditions – it is the coldest and windiest ocean on Earth. The latitudes from 50 to 70 degrees south are also known as the "Furious Fifties" and "Shrieking Sixties" due to strong winds and large waves caused by the winds blow that blow around the globe in those areas. This is not terrifying or something that happens sometimes, it happens mostly in oceans and seas, and the ship should face the wave head on, there's no danger for ships, I used to enjoy it every day when I was on ship. This is filmed on a modern warship with a motor. Imagine 300 years ago voyaging across an uncharted Atlantic on a soggy permeable piece of wood that depended on the wind. The wind whistling through the crow's nest as the sails rip and flap. Another seasick lad belches as the sea gives way to the eternal, frothy abyss, as the sailors pray, just pray that their ship reaches land. 1700s sailors were something else.
