It was clear from the start of discussions with trade unions that Manxman would be a live-on-board vessel.
That's according to the Steam Packet Company, which has issued a statement as it strives to reach an agreement with Nautilus.
It says the rationale for having crew live on board is that it reduces avoidable cancellations and improves operational flexibility.
Manxman was designed to include accommodation for crew, whereas the Ben-my-Chree doesn't have the facilities.
The company says it wants to end the impasse around compensation for living on board vessels, and is making changes to working practices to improve service.
However, Nautilus International claims its members have been threatened with fire and rehire, and the Steam Packet has refused to listen to concerns about the detrimental impact living aboard will have on family life.
It added that members are asking that these changes be phased in and existing contracts are honoured.
