I have a 28 lb Kevlar canoe in the yard that would break an aluminum one. No reason not to run rapids in them. The real problems are bad hull design and seats too high if you are sitting as opposed to kneeling. Looking at the canoes the outfitter offers I am sure he gave you the wrong one's for your skill and technique levels.
The seats were VERY high. Only an inch or two below the top of the canoe, and the were round bottom, with no hull.
The outfitter was very aggressive about warning us about scraping the canoe bottom, doing fully wet exits, etc. There were signs all over h e place showing canoes with hoels etc and that replacement cost was $6k, so we didn't want to risk it.
