I ask the crew to get a far forward as they can and still be comfortable. If they are on the leeward side you will have to watch for any little puff as you could be flying your hull very quickly. After your weather hull goes in the air and you are sheeting out while your crew is scampering to re-balance the boat you have lost lots of forward momentum. Best in these conditions to keep the crew near the mast just below your placement, which is near the front crossbar. This is for the Tiger. An Infusion likes to have the bow pressed down in light winds and it kind of needs the crew out on the leeward hull. This can get tricky in puffs.
