I'll see if I can get some pictures of our ski racks up if I can. I don't know if they will be of any use to you or not. They were designed by the guys at Wasatch Powderbird Guides years ago. I know if you tried to get a 337 on them now you're out of luck. The process might be easier down there. The ones we use on the L-3/L-4 weigh 15lbs (around 7kg). It doesn't really affect the speed of the ship the way a basket does, which is a bonus as far as the 206 series goes. Let me know.
