I found this picture in a railroad schedule from 1925. It’s kind of hard to tell how this worked, but I’m guessing that when it came time to watch the movie, people gathered on the embankment and saw the film to the accompaniment of the crashing waves. Or maybe it was more like a watery drive-in (a float-in?) at high tide, with viewers rowing up or simply paddling in on their surfboards. It sounds wonderfully dramatic, but I would imagine that with all of the noise and the motion it would be a little hard to follow the story. It could be that there was a reason why this was the world’s only one.
