Speaking to the club's official site, Chairman John Berylson said: "We are pleased to welcome Euroferries Express on board for the 2014/15 season and beyond.
"Throughout the whole process of finding a new main partner, the most important factor was to make the right decision, not only to safeguard all that is good about our club, but to ensure the chosen company possesses the qualities we seek to follow previous trusted partners.
"That has undoubtedly been achieved, and I look forward to working alongside Euroferries Express throughout the duration of our partnership."
Adrian Gillan, Euroferries Express Director added: "At Euroferries Express we look forward to bringing additional access and opportunities to the club to help build on its current fan base and highly acclaimed work within the local community.
