Also, if you are "pinching" (pointing too high) and the others are not, you will not fly a hull while they do. Do you know their crew weights? They might have been sailing with lighter crew.

Was your traveler centered? Was your mast rotated enough? For more power, rotate the mast a bit more, (or less if it is way out already) see what happens. Cunningham, on just enough to remove wrinkles, no more until you get over powered. Where was your out haul, out tight or loose enough to give you some power? Also, if the top of the sail is flat with little pull on it, try pushing the top batten in tighter, to force some curve into the sail.
