In the 2015–16 season, Marine had a less turbulent ending to the league campaign culminating in a 15th-place finish. Trusting in many of the players that ensured the club's survival the previous season, the club started the campaign well but with the weather leading to many postponements the winter saw not only a disjointed fixture list, but also a run of poor performances. Marine gained more stability in the latter stages of the season and this in particular led to a strong performance in the league cup, beating Glossop North End, Ramsbottom United and Workington to progress to the quarter-finals. A home draw saw Ossett Town narrowly beaten 1–0 before Colwyn Bay were drawn to visit Rossett Park in the semi finals.
