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 a 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!)
