You hardley ever sail a Hobie dead down wind without a spin. Usually they broad reach. This is thier fastest point of sail so the apparent wind is much farther forwrad than on a 30' sloop.
Keep in mind that loose footed and boomless are two different arrangements. Loose footed mains still have a boom, but the foot is not in a track along the top of the boom. It is only connected at the clew.
