Tuf Wakesurfs have been designed based off of what our customers have asked for. Personally, I would imagine that the majority of wakesurfs, we have built to date, could be used as River surfboards or even as a ocean surfboard. As of now, I have not been able to demo or have I received any reviews, stating that any of these models have been used in rivers or oceans. At Tuf Riverboards we can build what you want and make sure your design is going to work in your desired conditions, our wake surfboards are a good example of that.
