First know that I am not a kayaker, I do spend a great deal of time solo canoeing on Class I & II rivers paddling WITH kayakers. That said, I see a lot of people having fun in cheap Pelican kayaks and they seem to do just fine. (Any boat is better than no boat.) I should point out that I don’t know how these boats hold up over the long haul. I think you’ll enjoy kayaking more with a better designed (and probably much tougher) rotomolded polyethylene boat. For Class I & II, I THINK you’ll be happier with a 10-12 foot kayak. One thing I do know is that if you’re not using a spray skirt in Class II water, you will get plenty of water dumped into your lap. You’ll probably have an easier time finding a skirt for a better boat than you will for a Pelican. Remember, I canoe. Anything I tell you comes from casual observation and not from actual experience. Others here will be able to provide better advice. I just happened to be first.
