A large gray ship in the middle of the ocean

I need a background png image for my mobile game called battleship which does allows users to play the classic battleship game with images of slightly rough sea with war ships and carriers on it. It should show a 2D Grid with lines running both vertically and horizontally and should be very visible so make its background darker to make the lines pop out a lot more. No human in the image
