I just tried putting stick steering on my little 12 foot aluminum boat. I found that it made a nice boat out of a 12 footer due to the fact that it kept all the weight off the back. It didn't plow at all up front, even with me in it by myself (215 lbs.). The steering was very smooth and it doesn't slide in sharp curves very bad at all.
Just thought I'd see what you guys thought and give someone maybe an idea if they have a 12 footer they find annoying like me. Here's a link to about a 30 second video of it running if you're interested:
