Corrected entry: When Jack and Rose enter the water and everyone is still splashing around, a speedboat and banana boat can be seen quite in the background.

Corrected entry: Jack hoists Rose up onto the railing at the front of the boat, and they stand there for several minutes. Having been at the front of a boat in San Francisco, I can say that the Jack and Rose would have been blown back and unable to stay on the railing due to the speed of the ship. Instead of a small breeze in Rose's hair, the wind would have been pushing them backwards.
Correction: No, they can't, because they don't exist. The scene was shot in a tank, indoors. The more distant swimmers are CGI, as is the rest of the background, which is pitch dark. There are no such boats.
