The photo the lord posted brought back momeries.
In august 1970, I was sailing to south-west France (okay: not only me but 90 soldiers on two coastal minesweepers).
We interrupted our trip close to Boulogne-sur-Mer, because of severe gale storms in the Gulf of Biscay
- 4 août 1970: une tempête ravage en quelques heures 300 kms du littoral atlantique: 5 morts et 7 disparus. Plusieurs centaines de bateaux coulés, tous les terrains de camping dévastés, des centaines de voitures hors d'usage, des milliers d'arbres arrachés.
Just a day later, all was calm ... until we "turned around the corner" (Bretagne): there was no wind (just 2 to 3), but a wave height of sometimes more than 12 metres ... from abaft, which made our helmsmen mad. And the engineers as well. (And I was ordered any couple of minutes "to make weather".)
(According to 'globalsecurity.org', our boats were "a very robust and versatile boat class".)
