Allow me to start with the disclaimer that I have done searches for chair, seat, backrest, canoe seat, and did not get any hits of interest. ( I find that hard to believe; maybe I'm not searching correctly?)

For our upcoming trip, we want to entertain the thought of outfitting the canoe seats with some type of backrest. I already have one of the Crazy Creek chairs that we used on a three man trip for the “spare” person to use, and would like to attach it (and one other that we’ll need to buy yet) to the canoe seats for some added comfort during those strenuous long hours of fishing. Single portage trip, so the added weight will not be much of a factor. We already have a plan for getting the chair attached to the canoe seat (SR Q18.5 with the semi bucket type of seats); just wondering if anyone has any better recommendations than the Crazy Creek chair.

It will be interesting to see what this thread generates. I'm not aware of any seat backs for tractor buckets, tho there must be some. I use 'sit-backers' in my canoe, very comfy, but they are made for use on bench flat seats. One option might be to change out your seats. Another might be to shorten those grueling fishing sessions to about 30 min.

I've been using this one on my Prism for about 5 years now.  If you have any questions, I'd be happy to answer them.

This particular model has two straps that lash under the seat to hold it firmly to the tractor.  The two "side" straps attached to the back will need to lash to something roughly even with or slightly forward of the front of the seat.  (This isn't a natural lash point for the Prism with the slide-mount tractor seat, but by adding a nylon strap loop somewhat loosely around the slider rails in front of the tractor seat you can accommodate this issue.  I originally added "wings" made of short sections of conduit to the front chair support for this purpose ... the conduit fits the aluminum tubing just about perfectly... but this solution adds more weight to your canoe, albeit at the center of mass for a Prism.)  The seat also comes with two Velcro tabs and "belt loops" so you can secure the seat back to the seat when portaging (or parking for the night).

The downside of this design is that it doesn't work well as a stand-alone camp chair.  However, I sometimes use mine with a small folding (Coleman) camp stool.  The bottom straps go under the the aluminum tubes that constitute the stool seat and the side straps attach to the "U" of the front legs.

I've used the bucket seat you are refering to in my Spirit II. Yes it is comfortable when adjusted properly. But I found that it tends to shift around and causes me to sit too far forward. It does not allow my large hind quarters to get the full benefit of the tractor seat. I found a better solution to be the gel seat and backband I purchased from Wenonah. The gel seat stretches over the tractor seat and secures with a sinch cord and is easily removed. The backband attaches to the frame on the back of the seat and has 2 adjustable straps that run forward and attach under the gunnels (I found it more secure to attach them to footman loops rivoted to the inside of the hull). This setup is very comfortable and supportive. This is ideal when used with a foot brace. I can put a lot more power into my strokes and corrections.

I installed one of these in my Prism last year & it does a good job:   (You need to Login or Register to view media files and links)
