Up to 3,000 holiday-makers have had to revise their travel arrangements after a mechanical problem forced the cancellation of two scheduled ferry sailings between Ireland and France.
Irish Ferries blamed a "technical difficulty" on one of its ships, which required maintenance when it docked in Cherbourg on Monday.
The ferry was expected back in Rosslare early today, more than 12 hours later than expected.
As a result, yesterday's 4 p.m. sailing to Cherbourg and today's return trip both had to be cancelled.
Irish Ferries said it was accommodating affected passengers via "landbridge" routes through the UK, using channel ferries and sailings to and from Welsh ports instead.
A spokeswoman added that the company was issuing meal, hotel and petrol vouchers to the estimated 3,000 passengers involved, as well as reductions on future ferry travel.
