If you sail near the Atlantic coast of France or if you plan to visit Europe in the summer you should consider to sail to Brest in July (13-19) I mean if you like boats
They have another edition of their nautical festival: "Tonerre the Brest", a special one since they are celebrating its 20th anniversary.
Brest is in Brittany and Brittany is the home of the French sailors, I mean most of the great French legendary sailors are from here and none other French region is linked to the sea as Brittany. There are few other places as appropriated for a big nautical festival: It is not only boats, but the ambiance, the architecture the food, the wine and the beer. If you go there don't miss Quimper, Saint Malo (the corsair city) and Rennes.
