Maintenance routine is to store it upside down and high so it dries, always out of the sun. Twice a year I brush dirt out of the ash gunwales and apply teak oil. Every year or so I lightly sand out the ridges left by gravel and rocks and sometimes apply some polish.
It fell off my truck once so there are a couple places with very minor epoxy repairs, still haven't fixed that dent in my truck yet.
However, I love the boat. I use it for workouts on local rivers and lakes and for exploring. Although no longer competitive for racing, it is very fast and efficient. Efficiency means you can go farther and see more in a 2-hour paddle. It tracks, I lean it like a kayak to turn. I agree with the comment about secondary stability-I am not comfortable in large waves (though I have surfed motorboat wakes). I also like the comment that a boat like this deserves a high-end paddle (mine is carbon ZRE). I think it is good looking and I still get comments ("jeesh, what an intense canoe"). The workmanship is fantastic, it still looks new except for some Seattle moss and a little wear on the bow from paddling though ice sheets on local lakes. I will never sell it.
