We sailed across to Catalina and I jumped in the water in Doctor’s Cove to begin the swim to Palos Verdes.The water was choppy, but I made it ten hours without incident, and was feeling strong. At that point the captain received a radio message from the US Navy informing him that we had to change our route to avoid submarine maneuvers in the area. This was not only going to add an extra hour to the trip, it put us squarely up against a strong current. As the weather worsened and whitecaps made it difficult to swim, the observer determined that is was necessary to stop. At this point I had successfully completed 18.9 out of 21 miles: fifteen hours of freestyle swimming, beginning at 10:45pm. It was a grave disappointment, but the decision was not mine to make.
