Our go to hunting and local fishing canoe is the Mad River Explorer, it is like a fat mans Prospector. Ours is the top of line kevlar with the built in skid plates. It is a vee bottom, which inhibits its shallow running at times, but it is very well behaved in current and waves and it tracks straight with very little stearing effort. The Souris River Prospector has a round bottom, but it is not so rockered in the middle, this gives better glide and straight tracking that a standard prospector does not have. The ends come up quickly which allows it to turn in current very nicely. Souris River kevlars have harder epoxy than most other kevlars, it takes more to hurt them. Souris River canoes as a whole, can handle heavy loads very well. For big loads and big people the 17.5 version makes just about the best around canoe there is, but you do need to know the Bill Mason strokes. When I paddled the 16 footer, I laid it over. it has superb secondary stability. The 16' Quetico version while it makes a better fishing canoe and has more initial stability, does not like to be healed as far. I guess it all comes down to how often you will be going solo and where you are going go with it. I would recommend getting a midsized rubber back pack. Not for carring stuff, but to put water in to give you some foward ballast when paddleing solo. A rock in the front is not the answer, water is heavy, it will not damage or sink your boat, and if you do swamp the air space left will suspend your canoe, if the pack is tied in tight. For solo tripping I used to have a Wenonah Prsim, they are good up to 500 pounds, but are no fun running down stream in tricky currents. Going solo with the SR I think my cruise was about 2 mile per hour, tandem we were comfortable at 3 mph. We added a third person to duplicate a heavy load, and that 3 mph was pushing it a bit.
