I don’t have any knowledge of crew club and how their protocol works, but I’m part of another sports club at Iowa State and there is not a ton of oversight. I’ve been a member for over a year, I couldn’t tell you who our faculty advisor is and we don’t have a coach. My sport is significantly less dangerous, but I’m surprised how little oversight there is.
A long time ago the trap and skeet club ran with minimum supervision. Shot over at Boone (Izaak Walton maybe?)
