the process. Standing on the centerboard and "piggybacking" of crew members can be highly effective to right a turtled dinghy, as it increases both the weight and leverage being applied. Use of powerboats to aid is problematical, and depending on the technique usedthere are severalmay or may not succeed. See Capsize. Rigging righting lines depends upon proper placement, and critically should be done in advance of the need to use them. Multihulls In yacht sailing, multihulls are deemed to be more prone to turtling than keeled monohulls, and there is essentially no way to right them if they overturn. The juxtaposition of the hulls and sail when turtledit makes them inherently stable when invertedmakes them especially resistant to righting. Consequently, some larger multihulls are built with a turtle emergency escape hatch beneath the hull. Indeed, some locales require such safety hatches. There are, however, those who feel that the likelihood of a capsize of a large multihull is overrated. There are others who state that a self-righting multihull is the answer, along with designing in safety and proper operation. A patent has been issued specifically concerning righting of turtled large multihulls. It is intended to avoid the necessity to use divers and special equipment in a recovery. It is, however, possible (and often successfully) to right a capsized small multihull, e.g., a Beachcat and Hobie 16. The process begins with positioning ropes so that the crew can get leverage (acting together is key). Righting Beach catamarans that are turtled can be extremely difficult. Loss of sails, rigging, masts and boats can occur, not to mention sailors. A singled-handed self-rescue can be assisted by filling a garbage bag (called in this context a "righting bag") with water, and throwing it over the rescuer's shoulder. See Hobie 16 which suggests sitting on the rear of one sponson, which will upturn a turtled Hobie. Even some large multihulls can be righted at seait is a long shotprovided that the skipper is well prepared, knows what they are doing, and has appropriate devices, tools, skills, a workable plan, cooperative waves, weather and wind, and some luck. Notable events The Fastnet race, and particularly the 1979 Fastnet race (the disastrous race that changed yacht racing for all time), has been the occasion for many sailboat capsizes, turtlings and fatalities. In the 1979 race, "15 sailors died, five boats sank, and at least 75 boats flipped
