From around 1973-1997 there was a time when Irish Continental Line/Irish Ferries operated a direct passenger car ferry service from Rosslare Europort to Le Havre, France and also a annual summer service from Cork to Le Havre (in addition to their former Cork to Cherbourg annual summer service).
Why did Ireland cease it's direct passenger car ferry & freight services to/from Le Havre all those years ago?
I understand Le Havre is the 5th largest port in France in recent years.
Nowadays we have the following Ireland to France sailing options:
Rosslare to Cherbourg (Irish Ferries),
Rosslare to Cherbourg (STENA Line)
Dublin to Cherbourg (Irish Ferries)
Rosslare to Roscoff (Irish Ferries)
Cork to Roscoff* (Brittany Ferries)
*service to be expanded with chartered vessel "Connemara"
Cherbourg and Roscoff seem to be the current flavours of the month but I'm surprised there is such a lack of choice when you could have other options too including ports like: Le Havre, St. Malo, Saint-Nazaire, Brest or other options.
