some folks seem to get mixed up with sailing a two sail boat under main only and a UNi rigged main only boat ,
The two sail reduced to main only will need drastic changes to get any balance in the boat , a designed uni rig boat will allready be balanced .
you can't really compare how to sail one to another , ones designed for the job one aint ,
I know there are a few exceptions such as dart 18 and dare I say it F16's where you can take the jib off and it will work (prob still with mast rake etc adjustments ) but they again are designed to do this
I can tack my uni rig on a sixpence (dime) without even letting the main out at all in flat water and mid strength winds , but there again all designed uni will behave different
can see any off that that twaddle will help , all two man boats i've sailed have had sufficient dewpowering controls to cope with any wind
