From an earlier post I made on the issue:

Mooring a cat is a risk. Just be clear... Hobie Cat does not recomend mooring.
Cats do not ride at anchor well and are jarred by even small wave action. The waves cause accelerated wear and movement of the rigging parts. Rigs can fall if the shroud wires, forestay or bridles come loose or are damaged. The boat needs to be carefully prepared and inspected often. Tape clevis pins and rings. Check bolt tensions. Keep the mast rig tight and restrict the mast rotation. Tie off the rudders tightly in the up position.
As the wind angle changes a cat can sail forward rather than slip sideways. This can cause the boat to pull up and over an anchor possibly pulling the anchor free or causing the boat to pitch pole.
I recommend pulling boats onto a float or dock that will absorb the wave action and allow it to swing at anchor. This also keeps the hulls out of the water preventing damage or discoloration to the hull materials. This is a bigger issue on fiberglass cats. They can absorb water and cause blistering of the glass and gelcoat.
