the mast out of the water may help speed the process, as the greatest challenge of righting a capsized boat is shedding the weight of the water from the sails. A helpful step, where possible (on a loose footed sail), is to disconnect the clew of the sail from the boom, which prevents the sail from scooping up water as the sail lifts out of the water. The bow of the capsized vessel should be pointed towards the wind so that when the sail starts to lift out of the water the wind can catch underneath the sail and help right the boat. Care is taken not to let the boat swing all the way over and capsize on the other side, frequently with the crew on the bottom. This is more likely if the boat is not pointed into the wind. Prevention There is a wide range of technology that can be installed or strategically placed to prevent or deter a boat or ship from capsizing. The various technologies rely on inflating airbags also known as lift bags which increasing the vessel's buoyancy with the water. There are many steps a crew can take to reduce the chance of capsizing, such as distributing the weight evenly and taking care during windy weather. Yachts Capsizing in yachts can occur when water is able to infiltrate the hull and decrease the vessels water and buoyancy leading to capsizing. Yachts can be deployed with a flotation system which is a series of strategically placed lift bags within the interior of the hull increasing the vessel's buoyancy and filling void space where water can collect, providing valuable time to remove the water, fix damage or evacuate. Large ships When larger ships such as cargo ships and tankers capsize or sink not only is recovery not possible but great environment damage can occur from spillage of cargo. Larger ships are being equipped with Surfacing System for Ship Recovery which is an inflatable device that is installed in the ballast water tank or within the hull of the vessel and can be deployed within seconds of an accident to stabilize the vessel and give more time for rescue and evacuation. Self-righting A vessel may be designated as "self-righting" if it is designed to be able to capsize then return to upright without intervention (with or without crew on board). The angle of vanishing stability, the
