I had the opportunity to try this out a demo events a few times and then a friend of mine won one so I had a few more chances to try it out. Overall I wasn't really impressed with the Tonga at all. The stability was ok but not what I would have expected for a board of this size. The quality also seemed to be not great either. Upon researching it seems this board is definitely a cheaper intro model so I suppose you get what you paid for. Probably a decent board for someone who wants a SUP without a significant investment and does not have plans to do more than lake paddling
Good for smaller sized beginners
Stability could be better.
