As much as I don't wish to see a catsailor revert to monodom, it sounds like what you are after (if you can stand sailing so slow after all this!)
P.S. there are boomless catamarans.
Would it be as simple as not using my boom? My mainsail is free-footed...I could attach my mainsheet block directly to the clew of my mainsail? I assume the disadvantage is loss of airfoil shape?
