The 21 Super Cat is the newest 21 Cat to the Haynie line. The main questions that get asked all the time is what’s the difference between the 21 Cat and the 21 SC? The 21 SC is basically the bigger brother to the 21 Cat. The beam on the 21 Cat is 8’ the beam on the 21 SC is 8’ 10” so it’s a much wider boat making it more stable. The sides on the 21 SC are higher than the original 21 Cat and the transom is also higher making it for a much drier ride. The cat sponsons on the original 21 Cat are much smaller and don’t have much V like the 21 SC does in return giving the 21 SC a much smoother and stable ride. So all in all the 21 SC is just an upgraded version of the original 21 Cat and believe it or not the 21 SC can do all the things that the original 21 Cat does so come see us today and let us build one especially for you.
