We don't have a sprit on our H340
The PO acquired a UK asymmetric with a dousing sock and the tack strap that wraps around the head stay. Rigging includes a downhaul to adjust the tack up and down, the spinnaker halyard, spin winches towards the rear of the cockpit and small blocks attached to each stern pulpit to be the fairleads for the sheets. We've only used it a few times in two years but it works well on beam and broad reaches in winds under 10kt, but on our lake, we don't always have long tacks to make rigging the thing up worthwhile.
