A boyhood Town fan, Grimsby-born Cartwright rejoined the Mariners at the beginning of the 2026-27 season from Premier League side, Hull City.
A familiar face to Town supporters, Cartwright previously represented the Mariners during the 2023/24 campaign, making 32 appearances in all competitions and earning the Club’s Young Player of the Year award following a strong first season at Blundell Park.
The Grimsby-born goalkeeper joined Hull City’s academy in 2015 and has since gained valuable senior experience through loan spells with Peterborough United, Wycombe Wanderers and, most recently, Hartlepool United.
The 24-year-old enjoyed an excellent spell with the National League side last season, making 13 appearances and keeping seven clean sheets before his campaign was unfortunately cut short through injury.
