No, they don't. Tandem kayaks - whether they're meant for fishing or not - are designed to be super stable. Most of them have flat bottom hulls and wider decks, resulting in unparalleled stability. That said, here are a few paddling tips that will come in handy: 1) Be deliberate about seating - the first decision you'll need to make is figuring out which angler sits where. Usually, the person seated at the front sets the pace while the rear-seat paddler follows their lead. As such, the individual who has more paddling experience should sit at the front while the less-experienced one sits in the rear. 2) Kayak in unison - no matter how long the kayak is, chances are that you'll be sitting in very close proximity. So if you're not careful, your paddles might keep colliding with each other. To avoid this, do your best to paddle in unison. The rear-seated angler has a better view of what's happening. So they should time their paddling strokes to match those of the front paddler. 3) Make course corrections from the back - even though the front paddler sets the rhythm, it's the back paddler who has the greatest impact on the course and directional changes. You may encounter situations where the yak starts going off course no matter how hard you try to paddle. In such instances, the rear-seat paddler will need to perform a backstroke on the side you'd like to go. They can then rejoin the front paddler with the forward strokes.
