actually i was (above) thinking tformex was the plastic. i now see it is sp3 plastic. the sp3 plastic, even if shortened to 15, will still be double the weight of a durable composite like swift expedition kevlar. whereas the tformex plastic would be much closer to that durable composite weight.
then again, NC doesn't make tformex boats.
so the pros15 plastic would have to be Esquif pros, which i wouldn't recommend (given the wanted initial stability, and wanted resistance to being spun by wind).
the NC pros sp3 15 is 90 lbs. so... going with the idea that it's too much weight (if not true, then excellent: you have a very cheap durable solution here), i would look at esquif recreational boats. maybe the esquif scout.

but generally, if you want to blow left-right less, and want to shuffle around in the canoe, giving stuff to kids while fishing, etc, while feeling stable doing so, as on a small square raft, then you want the bottom of the boat to be flatter, wider (like a raft). And less rocker (boat less looks like a banana from side profile) will help you keep on course, especially if boat is shorter than 16.
whatever you choose, a strong drybag 25L (becomes 50lbs, or less, if you require), can do so much to keep the boat on track, by filling it (the drybag) with water and placing it at front. it is my #1 choice when boating away from basecamp, just me bow reversed no packs (which is probably similar to you solo, as you're not in backcountry).
