Notes:

This was the first dive for the Underwater Navigator Specialty course.

On this dive I had to use a compass and swim 20 kick cycles due north, then make a 6 point turn with each side having 20 kick cycles ending up at my starting location.  This was very difficult with the current, but I finally managed to complete it. I also had to pick an object on the sea floor then take two compass bearings on it so that I could locate the same object again on a later dive.
