The fast passenger catamaran Snaefell, formerly the Sea Express 1, will start her summer service with the Steam Packet on Monday.
She has already been back to Douglas for trials since her re-branding with the Packet livery.
Her first run will be to Liverpool at 7.30am.
She is the sixth Snaefell to serve the company.
This year, each of the Packet's ferries will have a new Niarbyl lounge with pre booked seats available.
