Reefs and superstitious

After about 160 kilometers sailing north-northwest with coast of Brittany to starboard
– comes an area that previously worried sailors, before the electronic equipment era.
Traffic south through the English Channel sailed mostly this way
– traffic back and forth between the whole world except North America.
The area around Île-de-Sein at the “tip” of Brittany, there are lots of dangerous reefs
– led to lots of shipwrecks and as sailors in general were very superstitious.
Then women on the tiny island Île-de-Sein were blamed for these shipwrecks
(as always: is there only one(self) to blame, blame the women)
“They bewitched the waters by wearing black hats” was many seamens belief
