Could i be a good coxswain?

hi, so i am going into eighth grade and am looking into high schools. the one school i really would like to go to has a superb rowing program and i was wondering if i went there if i would have a chance to cox for them. i am currently 5' 4" and growing taller everyday but i only weigh about 85 pounds. i am extremely energetic and dedicated, as well as very loud! i have researched crew a lot and it seems coxswain is a huge responsibility but i think i am up for the challenge. i was also wondering if i go into my freshman year without any experience rowing is that okay?!? jill costello is my all time favorite role model and her story really inspired me to want to cox. any feedback or coxing advice would be helpful! thx!
