A large volume hull … I would say no. It is 16 foot for one. Most serious tandem trippers are 17 or a little better. I think the capacity is listed around 800 pounds, maybe a bit more. For most folks that is a good amount, BUT most folks like a little more and want more Space to put their gear. I think the Pal is a terrific canoe … but I am 6 ‘2 and 225 to 230. With myself, my dog and my kit I have 400 pounds give or take. The canoe at that weight is still pretty lively. It paddles well and maneuvers SO easily. I think if I had another adult and gear the canoe might start to feel a little loggy with a multi day tripping load…and likely feel a bit cramped for pack space. The Seliga is longer and wider, likely a better tandem tripper, but not as nifty as a tandem/solo back country explorer ( my opinion only ).
I used my Pal as a day paddler for my wife and I, a back water explorer for my dogs and I on the often flooded Wisconsin River bottoms, and like mentioned previously a dedicated solo for multi day trips in the boreal. My longest trip was in this boat, 32 days in WCPP.
If your primary mission is for tandem explorations the Seliga sounds like it may be a better option for you.
