My Hobie-18 and Nacra 6.0 responded well to this. The 18 was fun to sail that way - single handed in big wind - roll the jib up for upwind, roll it out for downwind. My Hobie-20 didn't seem to like it as much, and the jib is small enough on the N-20 to maybe not make that much difference.
On the N-20 a few times I have oversheeted the jib to close down the slot and the back of the main to slow the boat down. Not fast, but peaceful...
