A Smitty sled is just a pair of skis with 4 risers (6", 8", etc.) and 2 cross ties. You set your ice fishing hut or sled on the cross ties and lash it down with some sort of tie downs. The idea of a Smitty sled is to get your sled or hut up above the snow. Your picture shows what I think is a ice fishing box mounted low to a pair of skis. Try to advertise as a permanent wooden ice fishing box mounted to a pair of skis, you may have better luck getting a taker.
