The think the wild thing was an Aussie thing and has been around for some time this is from the internet from the AHPC web site on tuning

Medium Winds : 10 - 15 knots.
Ideal "Wild Thing" wind range.

Luff Tension - just remove the wrinkles down the luff.
Mast rotation - 80deg.
Mainsheet - firm to hard, ease the mainsheet in the gusts to control the power in the sail.
Foot - 100 - 150mm camber in foot
Traveler - set traveler 100mm. up from inner gunwale.
Steer down in the gusts and up in the lulls.
Move your weight back and to leeward to help lift the windward hull. The crew should be sitting on the leeward hull and the skipper on the windward hull. This also keeps the bow up and makes the boat easier to steer.
Jib barber haul - 400 from fully pulled on.
Jib sheet - firm to keep telltales flowing.


I don't see what is wild about just flying the windward hull downwind on a modern cat (a hobie 16 or aquacat that would be a little wild), until you add the extra FU factor of a body on the leaward side now you are asking for trouble and getting wild.
