At this quiet time of the year, vessels from Irish Sea ferry operators are taken off routes to undergo annual dry-docking, writes Jehan Ashmore.

In the case of Irish Ferries, their Rosslare-Pembroke Dock route vessel, Isle of Inishmore arrived on the Mersey yesterday at the Cammell Laird dry-dock facility in Birkenhead.

The 1997 Dutch-built Isle of Inishmore had relieved the 50,938 tonnes 'flagship' Ulysses from the Dublin-Holyhead route which too had gone to Birkenhead for maintenance since January 4th.

The Ulysses is now back on service and the company's French routes cruiseferry, Oscar Wilde is covering the Isle of Inishmore's absence from Rosslare-Pembroke Dock sailings.

Continental services to France on the Rosslare-Cherbourg route will resume on February 16th when the Oscar Wilde returns from her overall. The Bahamas flagged vessel will re-open seasonal Rosslare-Roscoff sailings starting on May 13th.

In addition to conventional tonnage Irish Ferries also operate the fast-craft catamaran Jonathan Swift in tandem with Ulysses on the Dublin-Holyhead route. The Ulysses takes 3 hours 25 minutes while the 39-knot catamaran craft marketed as the Dublin 'Swift' is advertised with a scheduled passage time of 1 hour and 49 minutes.

The Australian-built catamaran was taken off the central corridor route yesterday to be drydocked also in Birkenhead until January 18th. Dublin Swift sailings return to the Dublin-Holyhead route on February 19th with the first crossing to depart at 14.30 hours from the capital port.
