The Trophée Marie-Agnès Péron is a regatta that complements the Mini-Fastnet. A kind of exercise in style as are often single-handed sailing. The Iroise and Brittany have a range of coastlines, islands and narrow passages that generate very different sailing conditions. Advantage or not, the Breton sailor knows well these waters in general and the shelters are never distant or difficult to access in case of trouble.
