As @intparent said it so eloquently, many freshmen don’t build long-term friendships until their sophomore year. Many change as they progress through college. While you don’t have to adjust to someone else’s personality/approach, giving the activity a little more time tends to fix a lot of issues or feelings. Also, see if you could find something common with your roommates.
BTW, I am a new fan of rowing…it is an amazing sport. I just finished reading the book “The Boys in the Boat”. If you haven’t, check it out: https://www.amazon.com/Boys-Boat-Americans-Berlin-Olympics/dp/0143125478/ref=sr_1_1?ie=UTF8&qid=1510697429&sr=8-1&keywords=the+boys+in+the+boat
