because... we had a lot of boats going out, and the lower boats were using those crazy boats that have the cox sitting behind bow, which probably require someone more experienced. and we have a real dearth of coxes. plus we were being coached by a former german international, so we didn't expect anything that bad to happen.
we were going fast straight into a barge, the cox screams "WATCH OUT!!!", we all spin round (and so shift our weight), bow side have their blades forced all the way in, we fall in.
