It's a hoot watching the boats come and go through those locks. We watched a ~80' boat come in one day and the skipper had a heck of a time keeping it lined up with the lock as he made his approach (he was headed out). After he had to stop several times and shift engines to bring the bow to his port side it dawned on me that he probably had not turned off the auto pilot.
He kept bumping against the stbd wall as he came in and when he got about even with me where I could talk with him without yelling I asked him if he'd remembered to disengage the auto pilot.
He turned around, disengaged it and turned back to me, all red faced, and just mouthed the word "Thanks".
