Hi, not directly answering the question. I use a wire strop around the bow roller and connect a multi part down haul to this for the assymetric. It flys well and I adjust the tack length as needed. I've never worked out how to fit a sprit around / over the anchor locker with any of the available kits. As an aside I use the spinnaker pole to bring the luff to windward as you would for a normal spinnaker, the sail is very stable with little risk of wrap. Regards Doug
