Good luck with that. We have kayaks and wife had a paddle board. The last thing I would want to do is to try and get those things up there and down. Also as other mentioned, the potential to cause damage and the chance of water intrusion. Depending on the weight of your boards, look at strapping them to the ladder. Not sure if you will be able to or not. I know my wife's paddled board weighed over 40 lbs. We got rid of it because she decided she wanted an inflatable one and they are lighter. If you are gonna find a welded, get them make something out of steel that can go into your receiver. Have it like an open box and go up 4 or 5 ft. Put them in that strap them down.
