Can I get into the United States Naval Academy?

I am currently a freshman in high school and my dream is to become a midshipmen. I go to a college prep school that is academically challenging. For the first semester I had a 3.1 GPA. My father was a midshipmen and played football at the academy. I am good at hockey and my select team is one of the top in the nation. Also I play golf and most likely will be one varsity by the time I graduate. I am a student officer for a school club and will have around 90 hrs of community service by the time I graduate. In the PSAT I finished in the top 30% of college bound Juniors. What kind of chance do you think I have to become a midshipmen?
