They recommend flat lakes and not rivers for this kayak. I’ve done both and because this kayak is high pressure making it very rigid, it is pretty unstable. The sides are low and it doesn’t take much to tip especially for beginners. This thing is built for speed and not stability. I have taken the tandem down the Salt River in Arizona. Class 1 to 2 mostly and have never tipped but I’ve come close. I’m not a novice and have quit a bit of experience with this particular river at least. If you want to use it mainly for lakes it’s great but beware it’s not very stable for rivers.
It has several places to hook your seat. I go one person and a dog always
Thank you for your interest in our 473RL Razorlite Kayak. While our FlexBrace is adjustable, it is not removable. The 473 is designed for use with two people. We recommend our 393RL RazorLite Kayak which is designed for one person (AMAZON ASIN: B00PUZLWCA).
I have the RL. It's very easy to control. I prefer the skeg but it is possible without it.
