I just looked this up for a friend after a debate a few weeks ago. It is not referenced in the Wave Assembly Manual. The warning can be found in the "Sailing, Tuning, and Trailering Guide" on the Wave Resources page.
Wave Resources:
https://www.hobie.com/support/wave/Guide:
https://media.hobie.com/digital_assets/sailguide.pdfThe guide is not Wave-specific but applicable to all Hobie sailing catamarans.
"Hobie Cat does not recommend leaving the boat in the water on a mooring. Accelerated wear to the boat and rigging will be experienced. Damage to the hull material is possible. Limitation of the mast rotation and tensioning of the rigging are required to lessen this wear. Inspect rigging often and tape rigging rings and shackles to prevent loosening."
There may be other references in other Hobie documents but this is what I found.
There are also several good forum topics on mooring with tips and advice that you may want to look at:
