Ended up just going with stock Rad-A-Cage racks for my 2000 Mobius... Bought these just before I found those. Never mounted, still in the packaging.

Both racks are in the 1 5/8 mounting tube diameter and would presumably fit slightly larger.

Rack number one is a 1 wakeboard + 1 kneeboard or surfboard combo rack and the second rack is for 2 wakeboards or thinner wakeboards or skimboards.

$300 shipped anywhere in the lower 48.

$280 picked up north of Austin TX, in Round Rock.
