Sweet ride! I hope you have a lot of fun with it.
I used a canoe for many years, I had it rigged up as a one-man fishing machine. Caught a 46" gar one night deep in the heart of Texas. Then I started dating the woman who became my wife. We liked the canoe just fine, but we have a lot more fun in a 16 ft boat.
Speaking of steering, one thing that I rigged up on my canoe was a steering extension. But not on the tiller handle. If you get that thing extended 50", you have to push it pretty far to get any turning going on. I used hose clamps to attach a 5" right angle to the TM shaft. That piece of metal stuck out 90 degrees to the main axis of the boat. THen I got a 5 ft half-inch PVC pipe, ran a bolt through it and attached it to the angle. This way I could steer in the middle of the boat using a push-pull of a few inches instead of having to swing the tiller arm out over the side. But I love rigging up stuff like that--if you've got a system that works for you, that's great!
