Tom, I've seen that paper before and there's one item on there that I take issue with. They say to use a bow line and stern line. Nope, we do it with a single mid-ship line and it's much easier.
I also discovered the secret to being bounced around when you're being raised in one of our locks. I want to put a graphic together first so I'll get back to you on that one.
Wifey B: We use a single line too, just loop it around the bollard. We go overboard on the fenders.
The one thing I'm guessing you don't get too much of on the Columbia but I don't know is when you lock through with tows and other large vessels, be prepared for their prop wash. We've locked through a few times tied to one of them. That makes a real smooth ride.
And listen to the lockmaster well. He's done it a few times before and he'll help you every way he can. If you have any questions, ask them. If you're not ready, let them know you're still working on it. I felt so sorry for a pontoon boat one day in Guntersville Lock i think. The lockmaster was very patient though. At one point the pontoon had been swept around by the wind and was facing the wrong way. Most lockmasters are very nice though.
