A decent set of roof racks instead of the "foamies" and most should have little problem loading/unloading a canoe around 75lbs or so. I have an indestructible Coleman 15.5 that gave me trouble loading until I bought racks. Now solo trips are easy.
I'm no longer lusting for Kevlar, especially after I spent a week in McConnell Lake beating the snot out of the Coleman. A little clean-up when I got home and it is still good as new.
Like some have said, think about moving up to 17' and try before you buy. Deals should be plentiful around this time.
Good luck,
Barn
