You could also contact your guidance department at your school immediately and tell them of your interest in women’s rowing. I remember an e-mail from my daughter’s guidance office saying, “If you are good at a sport that we don’t already know about, please let us know so we can help!”
I think the question is, which do you want more: To row on a men’s team somewhere or to get into a top tier college and row on a women’s team potentially? That’s a question only you can answer. But for now, I think you can still pursue both.
Edited to add: While she’s late in the process for recruiting for this upcoming fall, the timing is just right for her to redshirt on a team her freshman year, train, and then begin rowing fall '25.
