My canoe is build durable and came in at 50#, heavier than planned, but still light enough to portage. I will not hesitate to take on BWCA expedition but expect to paddle to keep up with good canoers in tandem tripper canoes. If BWCA is your main use then I recommend you build the Northwest Merlin instead.
The Passage is a very good all-around solo canoe.
Speed wise empty I can kick it up over 6 MPH in a sprint and on a fast cruise I can keep it up over 5.2-4 for about a mile before I tire out. at a steady cruise she will stay at 4.9 -5.0 for as long as I want. I have raced the Passage (XL)many times and have successfully beaten Advantages and some older Jensen designed white water boats.
The Passage is not a hard canoe to build and is fun to paddle. It is not a race boat though. You are not going to be competitive against a dedicated race cruiser so if that is your intention don't consider it. On the other hand for tripping, or if you are heavy it is a good option.
If I was over 220 pounds, I would give the boat a 8.5 or 9 but at my weight it doesn't sit in the water for adequate tracking. (of course the flip side of that is in the last race I went over the rocks with just a little scuffing to my varnish...)
