I solo my R-23 more times than not. I don't find a need for a second station at all. With the bow thruster, docking is easy. Even when others are on board, I often will get out and handle the lines so that my boat gets pulled in properly. (An inexperienced person will pull one line and bang the dock.)
For fishing, I have the Panther remote on my kicker motor. It handles steering. You can also add a throttle control, which would be super handy.
The other thing to keep in mind is that the cockpit isn't the biggest, so if you want to hang out and enjoy the sunset on the deck, you don't want to take up additional space where a chair and your head might go.
