Initially I had trouble deciding between sit-on-top or sit-in, and I'm glad I chose the sit-on-top, because it is safer for me since I kayak alone a lot of the time. If I tip, the kayak will not fill with water, which is a big safety and convenience issue. The only con of this kayak is the weight. It is heavier than others its size and makes it a bit harder to move around, but the stability is worth the weight, in my opinion.
All in all, a great kayak for fishing in rivers and lakes!
