Locks are a piece of cake to single hand, especially with a Hatteras MY with pocket doors which give you easy access to the midship cleat. One loop around the floating bit, pull tight, and tie it off. Done. I watch people struggle with spring lines etc. and just sort of giggle. I’ll set my fenders when I’m at the dock. If the current/wind is really bad, I just let them dangle. Otherwise, I’ll leave them on deck and toss them over when I get close. This boat has a bow thruster, which I consider cheating, but it adds to the easy factor. I took my own 58TC up the Tenn-Tom to Chattanooga by myself... on one engine. No thruster. Since then I’ve moved several boats through there by myself. Not bragging or trying to prove anything, it’s just something I’ve been doing for 40+ years. Let me add one thing. Locks where there are no floating bits/bollards are a bit more challenging, but still no big deal. Just tie one line to the forward spring, and keep the outboard engine in reverse until it’s done. Been there done that too. None of those type locks on the Illinois.
