Got this to carry a SUP, straps are definitely made for regular surfboards. What I did to make the strap work is by taking a 2'-4' cam strap, you cam the tail of the existing strap, then run the tail of the cam strap through the existing buckle. This actually makes the strap better, because it's easier to get good tension through the cam strap as opposed to the basic buckle on the existing strap. This way you can easily carry 2 SUPs. I do agree with the other reviews, dinging it for the strap issue, but for the price, it's a nice carrier.
