Mega Express 4 has more lane metres than Oscar Wilde had.
She was modified to increase her cabin capacity from 1950 LM to 1400 LM.
She is a sister of the Brittany Ferries Vessel Cap Finist?re.
No, the only real relationship she has with Cap Finistere is her original owners and their funnel design - this is the ex-Superfast II and the first two prototype Superfasts were rather different in lots of ways - less evolved hull shape, different shipyard, different interior designers, rather less opulent and less extensive passenger facilities.
Since then Corsica Ferries have bolted on the new accommodation blocks (Spirit of Tasmania added the nasty little conservatory type thing on the upper deck) and overall there's very little you would identify as common in the passenger spaces between her and ships like the Superfast V, VII, VIII and X which have sailed on Irish routes before.
Still, she is quite tidy on board but largely fitted out in Corsica Ferries' corporate style which has barely evolved over the past 40 years.
As built they had decent freight capacity and the ship had facility for twin level loading, which have never been used as none of her operators have ever sailed anywhere with the required ramps so own her internal ramps have always been used to get to the upper vehicle deck. The early refit with Corsica Ferries built cabins, reclining seat lounges and a new reception area into the aft upper vehicle deck which now means, at the stern, single level loading is the only option. I've not seen her bow visor operational for years and years but, as far as I can tell, it could plausibly work and there's nothing to suggest the upper vehicle deck door forward couldn't be made to work either - unless her owners have made modifications which mean this isn't possible. Best guess is she operates as a stern-only loader.
My point on compatibility with ramps is that this ship for almost all her career has operated to ports without linkspans, she just presents her on-board ramp to the quayside and parks up. As a comparison the Superfast X had her bow and stern access equipment rebuilt when she was on the Dover-Calais run which made her easily compatible for the Holyhead route. For a brief charter obviously they won't do that but they may need to tinker with things to make her fit properly, similar to what, if anything, the Epsilon has had done to her.
