Re: Tacking Asymmetric Spin
1. If your boat has the apparent wind pass astern when jibing, you must do an outside jibe. Rig the sheets outside the tack and haul them across just as the wind is astern. Leave a little slack, to let the clew float out in front of the boat, but don't run over the sheets. It is real easy to get and hour glass if you don't let the chute float out in front of the boat a little. Also, getting the main centered fast helps, as it eliminates the wind shadow. That is how we jibe our cruising cat.
2. If your boat is considerably faster than the wind (apparent wind passes in front of the boat, like a tack) you can do an inside jibe. My last 2 cats would do this and skiffs do this. You rig the sheets between the forestay and the tack. You really need a sprit for space. Jibing becomes a lot like tacking, much easier, but the timing needs to be sharp.
But having a sprit will NOT make it advisable to do an inside jibe. Hour glass city, since the chute will blow into the forestay. Inside jibes are for fast boats.
All that said, an inside jibe can work in very light winds, when the sail won't blow out in front as you would like. A crew member stands on the bow and helps stuff the chute through the gap between the tack and the forestay. Without a sprit and using and ATN Tacker, I can't see how you would manage it reliably.
