A sea anchor is designed to provide sufficient power to hold the bow of a vessel head to wind in the worst storm conditions. It should be deployed from the bow of the vessel and greatly reduces the risk of broaching, capsizing or rolling, keeping the boat more comfortable and stable throughout the duration of the heavy weather. Most importantly it allows the vessel to take the storm head on, rather than running with it, which reduces the time spent in discomfort. Typically a para-anchor would be fitted with stainless sinking chain to help get it launched as safely as possible and it would have a retrieval line. It would also be made of a strong high density, brightly colored nylon for high visibility in search and rescue situation. Every long distance yacht should have one on board. A range of sizes are available depending on the length of the vessel.
