The franchise played its first game on 2 April 2005, losing 24–23 to the Cologne Centurions. The Sea Devils' first win came in Week 3 of the 2005 season, with a 31–24 home victory over the then-struggling Rhein Fire.[1]
On 1 April 2006, the Sea Devils recorded their first tie in franchise history. At home, they scored 17 points in the second quarter, against the Berlin Thunder. They had blown their 17-point lead before regulation ended. When no one scored in overtime, the game ended in a draw. This was only the second tie in the NFL Europa history. The previous tie came in the 1992 season between the Rhein Fire and the London Monarchs.[4]
On 23 June 2007, the Sea Devils won their first World Bowl championship with a 37–28 victory over the defending champion Frankfurt Galaxy. It was also their last, as NFL Europa disbanded almost immediately following the game. As a result, the Sea Devils are the last team to win a WLAF/NFL Europe/NFL Europa game ever. [5][6]
