We took the weight and sail area of a typical 8m cat and lengthened it to improve the sea-keeping and speed, and widened it to improve the safety angle. This resulted in a 12m boat, 6m wide, SA 35 sq m, displacement 1,100 kgs. The main boom extends in front of the unstayed mast and has the tack of the jib attached to it. The jib clew is sheeted to a track on the boom in front of the mast. This results in a balanced rig requiring only one lightly loaded line to control it.
Easy sailing is a lightly loaded string to the ends of the boom, and a tiller.
Not quite point it in the direction you want to go and relax, but close. The drawback of unstayed rigs is that they need to be supported between a deck and a keel, or bridgedeck in the case of a catamaran. This still involves lighter loads than a conventional rig, but remains a hassle. It looks weird and it will unbalance the boat. We had already decided not to worry about looks, and I could not see that 2 long skinny hulls would be unduly affected by having the rig off to one side.
