Battle Foam releases foam trays for Sea Fleet games.
From their announcement:
The Sea Fleet Foam Trays are designed to work with the new Dread Fleet board game. Both trays will fit the entire content of the box and will allow for easy fit inside your official game box or your Battle Foam case. The 1st tray will hold all 10 ships included in the game and the large island terrain piece. The 2nd tray will hold the remainder of the terrain pieces along with game cards, dice, measuring markers, and small game pieces.
