Get bigger crew...or more of it. There is a reason why the weight limit is 1400lbs here in the states. And in the Carib its 1463lbs... and I try and max that out. We have 15-20kts most days and building... I have never raced with a reef in, but we can only carry a 155% when its "lighter" mostly a 140%. If you have too much crew and the wind drops they can go sit on the keel... make sure theres a couple of Sailing World mags for entertainment...and provide commentary from above to keep them happy.
