no-one will travel to ireland for holiday while lockdown measures are in place,
WB Yeats will remain on Dublin - Holyhead route until most likely August when goverment retrictions are lifted.
Swift will only be required at that point, in any case her charter options are slimb at this time.
As the 2nd New Build will not arrive for two or three years i expect Swift will remain in the fleet.
Its more likely some modifications have to be made to comply with Covid retrictions before she can carry passengers again.
