Lock up the rudders on any brand new cat (so they can’t kick up) and run it onto the beach and the same thing will happen. What is showing in the picture is not a construction issue...it is a maintenance issue. If the owner had maintained his boat properly he most likely would never have lost his transom (in both cases). Also keep in mind that a lot of the Supercats in use were built by
Boston Whaler 27+ years ago.
