How to hang waterski's and wakeboards for display

I have some old waterski's and wakeboards that I want to hang up, and I'm not sure how to do it.
I want them to be vertical.
I don't want to put any holes in them, or screw through them.
I would prefer it to look as though they are floating on the wall, so no visible hooks, brackets, etc... If possible.

Anyone done this? Any ideas?

They make those little metal circular "clips" essentially 2 disks that screw together that would squeeze the board then have a post on the back that mounts to the wall. Use to use them to hang thick plastic posters at tradeshows. Would prob work for a snowboard or wakeboard. You would put them on either side.

Or

Maybe make alittle shelf to sit them on and lean them against the wall. Maybe 2 small finishing nails on either side so they dont fall side to side.

Hope this helps.

I have a metal bracket I made to mount a snowboard on the wall. Then I just used the binding holes to mount it to the bracket which works fine if you want to show the bottom but you have to get a bit more creative to have the top show. I will be making a new bracket soon as I want to mount my old B-Side to the wall and want to have the top on display. Attached is what I am thinking of making and the snowboard in my living room. I made the last one out of 1" flat bar from home depot. I know a guy that can do some welding so I had him just weld a couple spots. You could probably just bolt the thing together as well.

I've got the wakeboards figured out.
I'm using a sleeve, actually a rolled pin that is 2" long, and I'll put a screw through the fin holes on the board, then through the sleeve, and into a stud in the wall. The sleeve will give the board the separation from the wall.
Probably have to use a washer against the drywall so the pin doesn't sink into it.

We used to hang snowboards in the shop with strong fishing line. Put a binding bolt in (or 2) in the insert(s) to tie the line to. Or you could use the fin holes...

There was a company a friend of mine used to rep that made displays that you could use. They worked with grid wall & scissored around the edges of the board. You would see the 4 black rubber bumpers that touched the boards edges, but thats it. (I can't think of the name of the company, maybe I can dig it up)

Some snowboard reps use guitar holders too. Although they are not super stable with a board on it.
