"I wonder how the Expedition would do in WW. A decked boat with a kevlar-S glass layup. Supposed to be plenty strong. Get it pinned though and it might be tough to get out as opposed to a Royalex boat that has some flex. Or it just might get a nice big fat hole in it. I guess a guy could bring plenty of rope and pulleys and a repair kit.
It doesn't look especially nimble though. I guess I'll find out soon enough."

18' of boat is not going to be too nimble in a rock garden - they don't seem to have any spec for rocker either - ?
