Despite the defeat, it was an encouraging performance from the Mariners as they continue their preparations for the campaign ahead.
The visitors took the lead through a first-half wonder strike by Mohamed Eisa, before former Town winger Siriki Dembele doubled their advantage with a little over 15 minutes to go.
Town asked plenty of questions of their own in attack but were unable to find a way past keeper Christy Pym, who made a string of great saves in the closing stages of the game.
