Love my Vibe! Went back and got a second one for my wife. The seat is very comfortable even after several hours on the river. We have been on rivers, lakes, and even the Chesapeake Bay! (Don't do that when it's windy) It's a very stable kayak. Light enough for easy loading and getting in and out of the river. Tracks well for a very maneuverable kayak. I think it's best on the river with rapids. For flat water you can probably find a better tracking, faster kayak.
