The company presented its new route from Cork to northern Spain today.
It will begin at the end of April and will link Cork and Santander, with two return trips per week.
It is the first ever link between the two countries.
“This is a significant move for Brittany Ferries, offering haulage companies a direct route to Spain and passengers a far greater range of holiday options from Cork,” said Hugh Bruton, general manager of Brittany Ferries Ireland.
The ship will carry around 500 passengers with space for 195 cars.
