Could be between 150 to 250 for the cap, no idea about the crew, you can try one thing, in the marina, at the long street with some bars and some marine
chandlerys there is a popular bar with some kind of old ships decor , very cute ,you know old binacles, some fishing
nets climbing from the roof , ask there for Manu, is a well know delivery
skiper in the area, he probably cross Biscay 100 times in any kind of vessels and in any kind of weather
, asuming you pick up the boat in sables d Olone, he charge hig , but hey !! Biscay .... i recomend it, is a profesional with all the licenses , is french, he know well Biscay and beyond south ... Try at night when the bar is full of sailors.....Good Luck in your croosing....
