We also made a visit to Teagle and convinced the rowing coaches to allow us to try out their ergs on slides. While we were there, we met William Tyler Nebel, a guy on the Cornell Men's Rowing team, who agreed to let us film him while he rowed. We noticed that the rower's body and the COM hardly moves while rowing on the ergs on slides. That is the problem with the erg on slides. We were also referred to Christopher J. Kerber, the Men's Lightweight Rowing coach, who is reputed to have a lot of data on rowing. We plan on contacting him sometime during our further research on the physics of rowing.
