Bob, If prefab seating is not available then I
would build a set. I have them on my H26 and will never own a boat without. Since I have the equipment to build them this is easy for me to say. If you know someone that can fab metal, then bending and welding up the framework would be easier that fortifying the coaming to mount them. You would have to chrome plate or powder coat the rails if they aren't made of stainless. Another posibility is to find a salvaged stern rail seat frame from a larger boat and section them down in size to fit your boat. Downsizing is easier than upsizing. If I can help more write backRayS/V SpeedyRay
