Down wind sailing.
Main and genoa out pooled, the jib
firmly sheeted as a stay sail behind the main. Closing the wind passage between
the forestay and the mast.
Quite a strong "artifical" wind in most downwind
Thanks to that wind across the bow, the staysail really works as a staysail,
keeping the boat steady a few degrees to leeward.
On Lindisfarne, rolling under down wind is almost only a bad memory!
