You shouldn't need crew to help through the locks. It's not hard, just part of the fun. If my wife and I can do it, so can you!
It's all on the one driving the boat
. Once inside the lock, it's usually easy. Waiting and holding position before entering has been more of a challenge for us, when there is traffic. Of course, they may squeeze you in between a barge and the lock. If they say there is room, there is, even if you don't believe the guy on the radio
. Have your PFD's on, and long lines set up before entering the lock.
Don't forget to call Gretna Light Traffic Control on channel 67 (locks are on ch.14) once you leave Harvey Lock. Don't drive down the middle of the Mississippi
. They get rather excited, and will tell you where to go. Compared to the Houston
Ship Channel, it's no big deal (but I guess they think it is in LA.)
