Me and my sister ones swam in the middle of the ocean. There was no wind, no boats and no waves so turned off the engine to try it out. We had a floating line in the water we could grasp if the stream took us with him. It was a nice experience, but we didn’t feel like doing it again. Anyway you should try it once. When there are other ships waves or wind it is not save to swim, and most of the time you have one of them, so it is not easy to do this.
