Hey Jimp.. That barge is laying flat on the bottom...

Try to imagine yourself hovering about 50 feet (maybe in a helocopter) above the boat looking straight down into the water...

You are looking right down thru the "open top" of the barge...

Does that help you understand what you are seeing...??

(Pm me if you need some 1 on 1 help interpreting what you are looking at in a SI image...)
