Hollow Spar Meaning in Sailing

The Horse Latitudes represent two regions of the ocean, located roughly at 30 degrees North and South, characterized by calm winds and high pressure. Historically, sailing ships would get stuck in these areas for weeks, sometimes leading to a shortage of water and food. The name reportedly comes from the practice of sailors throwing horses overboard to conserve water when the ships became ‘becalmed.’ One specific example involves a modern sailing vessel experiencing several days of still air and glassy water while crossing the Atlantic. Like the Doldrums near the equator, these latitudes are a significant challenge for vessels without engines. Understanding global wind patterns helps navigators try to avoid the center of these high-pressure zones. They are a well-known feature of the Earth’s atmospheric circulation.
