I sheet the boom right on centerline or even a little above. I try to have the top batten parallel with the boom. Having the main fairly flat with the maximum draft about 40% aft helps, too. If the main is too full, you will get more backwind. If the genoa is old and the draft has moved back to the leech, you will get more backwind. But overall a little backwind is to be expected and not really a problem. Andy C&C 40 Peregrine
