There was a trip from Rotterdam to the Med. years ago. It blew from Ushant to Cape Trafalgar like it does in the Atlantic. Around the mouth of the Bay of Biscay was the worse, one knock down and constant buffeting from 45 to 55 gusting 60-70 all day.
Half of the crew was spewing the other half was greenish yellow, most of them fair weather sailors. The captain was chewing his dinner, chorizo in one hand, bread in the other with a cuppa between his legs.
One of the crew asked him between two chucks:
'How can you eat and stand this, aren't you scared a bit?' He said: I'we been around the Horn six times, this is nothing compared to what we copped there twice.'
'What was it like?' the sick man asked.
'It is useless to talk about it - the captain said - you have to live thorough it, then you'll know.'
If one had some memories of similar situations, knows, and could give advice while the rest who might think they know and give advice regardless, or criticises, are akin to a fool.
