The Gaastra / Mistral ATS (Automatic Trim System) debuted in 1991. The sail below is a 6.9sqm fully CAM'd sail with a tight leech. What that means is this is very large and powerful sail that does not depower in gusts. What is especially nice about the ATS sail is that it is actually really easy to set-up. Traditionally fully CAM'd sails can be a real pain to get onto the mast, but this one is really simple and once on, it is very easy to tune (downhaul , outhaul, bingo!)
