If I'm solo on my H16 I can usually get a hull up in about 10 knots of wind; two people requires more wind. You'll have the opportunity to be flying a hull anytime the wind is foreward of 90° on the bridle fly, but usually when you're close-hauled is easiest.
Remember, you're not fast when the hull is way up though... the optimum hull "position" is just barely skimming the water. The hull on my H16 in the pic below is a bit high.
