Anyone know the differences in the two grading systems?

A friend has just come back from South Africa where (as a complete
rafting novice) he was running Grade 5. The kayakers supporting the
raft all went off to do a Grade 6 run in the afternoon. The numbers
seem a bit high to me.

Any ideas? Is a grade 6 raft-rapid actually a grade 4/5 kayak-run?

Having seen a couple of rafting company adverts in different countries
and having heard a couple of the raft guides talk to their customers, I
got the impression that they overrate the difficulty rather routinely.
Of course, they do seem to want to impress their customers... My guess
is that helps raise the tip.

Then again, there are some raft guides who run some pretty impressive
stuff with inexperienced customers, some of the big rapids on the Grand
Canyon and Zambezi come to mind.
