I am a beginner to sup'ping, and rented this board for an 8 mile stretch of a local river. The board was fast, stable and fun to ride. However, I found that it was challenging to keep it on track, granted I'm a newer paddler which could be the reason. There was a problem with the pump not pumping up the board and a new pump had to be brought to inflate it successfully. It appeared that a prior renter had stripped the connection on both the pump and the valve which made it impossible to inflate without two people.
