Which type of kayak is most stable?
If all other dimensions are equal, a sit-inside (open-cockpit) kayak is more stable than a sit-on-top kayak. In an open-cockpit kayak you’re sitting lower in the boat. Your center of gravity (aka rear-end) is at or near the level of the water. Open kayaks have scupper holes where water can drain out, making them more self-bailing than a sit-in kayak. And because their center of gravity is higher, sit-on kayaks tend to be wider and more stable. Because they’re more open, sit-on-top kayaks are great for fishing, as well.In the end, it all comes down to your priorities. Sit-ins are great for touring, cold water, and anyone who needs the speed and control of the traditional kayak experience. But for beginners, anglers, divers, or anyone who might hop out of their boat for a spell to enjoy the water, you can’t beat a sit-on-top kayak.If you’re floating on a river, you want a stable, sturdy craft that turns quickly. That might be a short, stable recreational sit-in or sit-on-top boat or day touring sit-in kayak. Rivers and lakes: If you plan to use your boat in both flowing and still waters, go with a short recreational sit-in or sit-on-top kayak.Greater comfort Perhaps one of the greatest benefits to paddling from a seated position is the added comfort. No more sore knees, no more pins and needles. Marathon canoeists paddle almost exclusively seated with their lower bodies braced to maintain comfort over long distances while still generating maximum power.The biggest downside of a sit-on-top kayak is the open design leaves the paddler more exposed to the elements. There is no cockpit to seal off from rain, wind or cold weather. The scupper holes that make them so quick to drain and easy to rescue may also allow water back up into the boat from beneath.
