Jerry,

You're right to be cautious, but you should be fine if only used for single handing. The thing to worry about is the rig, rather than the hulls or beams - assuming you can find some decent way to attach the wings to the beams.

Wings have the ability to increase your righting moment. The maximum force in the rig is limited by the fact that as the power increases, the moment of the rig will become equal to your righting moment, and the boat will start to tip over. The more you increase the right moment, either by becoming heavier, or by moving further away from the leeward hull, the greater the force in the rig before it starts to heel.

On the back of an envelope: when on the trapeze on an F16, your centre of gravity is about 11 foot from the leeward hull. Add a 1 foot wing and trapeze off it, and you'll increase your moment by less than 10%. Put a crew on the trapeze with you without wings, and you'll increase your moment by 100% - so I think you should be safe in 1-up mode.

Failure to do these calculations can be expensive, though - I've seen the remains of a Hobie Pacific mast after it was taken out 3-up in a force 6.
