When Gil Atkens (Wayne Rogers) carries the unconscious body of Sharon Renford (Stefanie Powers) down to the docked rowboat, Powers can be seen moving her right arm up Roger's back as he lowered her into the boat. She obviously felt like his grip was slipping and wanted to make sure she did not fall.
After Gil Atkens (Wayne Rodgers) places Sharon Renford's (Stefanie Powers) unconscious body in the front of the rowboat, her body is laying flat on the front seat. However, a few brief scenes later, her head is now propped upward against the rowboat's bow and her left leg is bent upward at the knee. Both body changes are very noticeable.
