I hate to use the dreaded phrase, but it depends. Most kayaks you cannot stand and fish in, plain and simple. Even those that say you can, you often cannot do more than stand up and look around. I am an athletic guy with great balance, and I have found that standing in kayaks and actually fishing is tough. Therefore, if you really want to stand up and fish—especially if you’re a big guy, an older angler, or someone with poor balance—you should buy an ultra-wide, exceptionally stable kayak.
