Which brings up a problem, and perhaps the reason the 10-step scale
has fallen into disuse: if the rating of the rapid must be changed to
suit the craft, then you are not actually rating the rapid, *per se*,
you are rating the rapid/craft combination. By contemporary thinking,
the difficulty of a rapid should be intrinsic to the rapid, measured
by objective criteria, and irrelevant to the nature of any craft that
might attempt the rapid.

I think we should rate rapids based on a combination of both the rapid, the
boat, and the paddler. For instance, there is a rapid, that shall remain
nameless due to embarrassment, that flips me every time. It's "easier" than
many other rapids I paddle, and I've done it a few dozen times, and yet, it
flips me. I think it should be at least a V.
