I always come with questions.........You mention the value of a sliding seat for trim, so while sitting in the middle of a solo with no second canoe around to eyeball your trim, how to you know whether it  is out one way or the other?  How it handles? Intuition?  Shadow of the waterline  seen through the hull?  Camper bubble lever glued inside the hull?

Truth be told I don't really care what my actual trim is- just move things till it works right. If I want to get an objective idea I can always consult the water in the bilge (from boots, rain, or paddle drippings).
