We have modified a Long Haul sailing rudder to fit our stainless kayak Rudder mount. The result is better performance for your sailing kayak. Overall measurements are 21" tall x 8" wide. This will fit a variety kayaks as well as folders including Folbot. The kit includes a SYK stainless steel rudder mount , 6 # 10 x 3/4 SS Screws and an anodized aluminum Long haul Sailing rudder assembly as shown. Steering lines not included.  Please add lines as per 3rd pic: (2) steering lines along with a  (1) raising line through the upper hole in blade and (1) down haul line using lower hole in blade for use while sailing (this prevents the rudder from swimming back as you increase speed). You may need other fasteners. This rudder mount will fit most kayak sterns. If in doubt text  (802-456-8165) us a picture and we will check it out. You do not need this mod if you already have a Long Haul or Klepper kayak. Check out the stock Long Haul sailing rudder here.
