What is the most challenging and enjoyable gait for a helmsman? Without a doubt the butterfly one. In a simple and convenient technique, we explain how to sail with the butterfly jib, helping you with the tangon.
Sailing astern: the butterfly
In medium wind, flush stern, concentration must be at a maximum to avoid deflating the jib or encouraging unintentional gybes, which are never pleasant. When the wind increases, and with it the wave, the sensitivity of the helmsman is crucial if you don’t want to end up with the boat by the hat. Certainly, in cruising, it is an easier gait to manage, especially with a less experienced crew, than the spinnaker stern.
How to sail the butterfly jib with the help of the tangon
In its “basic” version, the butterfly involves sailing with mainsail and jib on opposite tack, with the wind perfectly aft. The advice is to set up a boom restraint or at least a brakeman to prevent dangerous jibes.
But the “coolest” way, which is making a big comeback, is butterfly sailing with the use of a tangon. Not only does it stabilize the jib, but it also allows you to go to the grand slack with both sails free.
In fact, normally the mainsail creates a covering effect on the headsail.
By setting the tangon, governed by the luff, downhaul, and windward and leeward arms, you can move the jib tack point to the imaginary line perpendicular to the bow (and even beyond) with a double benefit: you will have the air on the jib cleaner and you will prevent downwind passage of the jib even at tighter angles than the stern.
