Hull speed is not a fixed point in time and space. I think the amount of engery required (supplied by the wind) to make the boat go just a smidge faster might be 1/16 HP (for lack if really knowing the terms) when you are at 1/2 hull speed to 10 hp at full hull speed. A sailboat can go faster that the accepted formula dictates even on it's own but the ol' 1.34(SQRT LOL) gets you close enough that the average sailor takes no notice. My Lancer is a"limited" to 6.6 knot but we had it to 7.5: screaming along. Then I checked the currents in the bay and delated my ego. We were using a GPS which only accounts for ground speed. SO . . . we were actually at 5.5 knots which for an inexperienced crew on a GORGEOUS November day, we were doing quite well.
As far as the jib only . . . poppycock! A freshening breeze, about 18 knots, we raised the jib only (because EVEYBODYelse was doing it and we were the least experienced on the water) and FLEW up the coast to Jewell Island in no time flat. It works great.
