Deeper locks downhill

We are now free of lock-keepers. The downhill locks are automatic and operated by sensors. But they are deeper and a little harder to drive into. Andy, at the helm, loses sight of the lock long before the barge enters it. We suddenly felt like novices again as we tried to learn the best way to approach the lock, tie up, jump the ropes down and keep clear of the gates and lock sill. There just isn't room for error. And we experienced a few bumps before we were truly comfortable.
