Short waterlines decrease weight capacity but can help a kayak pivot and surf better on rivers and in ocean waves.
Wide boats are more stable but also slower.
In other words, there's no such thing as a fast flatwater boat that is also a great, stable whitewater craft. All IK's in our two whitewater sections are self-bailing. To be sure, we don't try to carry every brand of inflatable kayak. There are some European models we've never even seen. Several points may keep something out of our selection.
