I have owned a Discovery 164 for a couple years. My wife and I take it on local rivers. I am not sure how old my boat is. I know it's royalex version. My boat seems to be different than the current models. My boat has a non existent rocker., it is basically flat from front to back. I do not care for this boat, it is not very stable. I am a relatively experienced paddler,. I have had so much trouble keeping this boat upright. I assume that this boat is more for lakes than it is for rivers. It tracks well and is pretty maneuverable. I don't recommend it for rivers with obstacles and rapids at all.
