I believe that boat would be a good choice.  I've met the owner of Superior Canoes, and if you are anywhere near the area, he almost always displays his boats at the Quietwater Symposium at Michigan State University the first weekend of March.

The Sawyer boats that are on the website are his attempt to revive the previous Sawyer Canoe Company.  He purchased the forms several years ago and is currently making those models.  One of my canoes is an old Sawyer and they are great boats.

The Superior is very much like a Kruger Canoe.  I have put my 17foot solo up against those boats on several occasions during the Hugh Heward Challenge (an event started by Verlen Kruger).  While those boats are heavy, they are fast and efficient.  Those who have them and paddle them love them.  I do believe that the Kruger Canoes are alos still being built.

If you get a chance look up the book "All Things Are Possible."  It is a biography about Verlen Kruger and would give you a lot of insight regarding that boat design.  

Good luck and enjoy your journey!
