That's how I see them, I paddle canoes, kayaks and even own a rowboat.
Additionally, when I look to get a workout from paddling more often than not the GRB Classic XL stays at home, and I get the paddleboard. Don't get me wrong I won't get rid of my canoes, but the paddleboard definitely has its advantages, especially giving a more complete workout.
