W. B. YEATS doesn't appear on the schedule either, does that mean they've sold her?
. Theres no vessel on the France schedule at all yet, does that mean they've sold Oscar as well?
The logical explanation could be that Epsilon is on the France schedule. Which hasn't been released yet! W.B. Yeats would likely be more suited to Holyhead earlier in the year anyway, when tourist numbers are low on the France route and when she's most likely to have teething issues (not to mention that this was the plan all along!). They probably don't dare put Yeats on the timetable until she is delivered to ICG's satisfaction after the fiasco earlier this year.
My money is on Brittany Ferries Normandie or Etretat assuming Honfleur does not suffer a similar fait to WB Yeats. A lease between April and October 2019 would cover Dublin Holyhead or Rosslare Pembroke sailings while WB Yeats operates to France.
The arrival of Honfleur will likely see Baie de Seine going back to DFDS. Why would Brittany Ferries leave themselves a ship short over summer by loaning it to ICG? The Brittany Ferries timetable is already out for next year, with Normandie operating to Caen until Honfleur's arrival in mid-July when she replaces Etretat at Le Havre. So even IF Brittany Ferries had a vessel available it wouldn't be until mid-July at the earliest which would be pretty useless for the hypothetical situation you describe
In any case, it took me a whole 5 minutes to find out the following.
"The charter-in of the Ropax vessel MV Epsilon will expire in November 2018. The company has two further one year options on the vessel."https://otp.investis.com/clients/uk/icg2/rns/regulatory-story.aspx?cid=500&newsid=986466
Its likely that ICG have extended the charter by a year given that it is December next week and she's still on the schedule!!!!
