maybe - but I doubt it. You would certainly loose the ability to flatten the sail (important for pointing ability and depowering in heavy wind) if you didn't have any modifications made to the sail. Boomless sails are cut specifically for that...usually the sheet attachment point is much farther inboard (and adjustable) than on a sail with a boom. The Nacra 6.0NA, Nacra 5.5, Nacra 5.0(?), and others are designed without booms. You can probably have your existing sail modified for this purpose without much loss of performance however.
