I have not done it myself, but I know that many of the NY canoe manufacturers who design sit on bottom, pack canoes do now have these types seats. Hemlock canoes and Placid Boat Works both install these types of seats. I am sure they would be extremely helpful in answering questions as they have proven to do so int he past. Charlie Wilson, is a well known canoeist in these parts. You will find him on adkforum.com, he is a wealth of info and has worked with many of the canoe designers (e.g. David Yost) and manufacturers. Last I know he was working or consulting with PlacidBoatWorks. He always gives great info.
