But leech flapping doesnít have much to do with sail trim. It indicates sail age. Usually however there will be a leech line that can be tighten / loosen to get the leech to the right shape - not flapping and not hooking too much.

Re: What am I doing wrong?

As already said, flapping leech is a sign of distortion along it.
The cloth is stretched.
Leech line can help but only to small degree as it closes the leech and creates a turbulence in the area, so you need to tighten it carefully.
New sails on the horizon😭

Tell tales are not happy!
Looks like sheet should be tightened more.
Or the sheet is running aft too much.
Try to get it more forcing down to tighten the leech.

Re: What am I doing wrong?

Seems like a self-tacking jib, right? You donít have much control with that, you can try rigging a temporary line from the clew to a strong midship point and play with it.

I would argue that the bottom is too full and the clew needs to be pulled aft.

Re: What am I doing wrong?

I'm with Ronald above, turn down or sheet in till those tell-tales flow back instead of flopping around.

Re: What am I doing wrong?

The biggest issue is that you have too little downward component on the sheet which means the sail is way too twisted. To go further: the angle of attack of the sail is very different at the bottom, middle and top of the sail. You’ll only be able to get one of these 3 sets of telltales working properly.

You need to either change the sheet attachment position on the sail, move the sheeting point forward (slide track if you have one) or add a barber hauler.

When the sail has the correct amount of twist all of your telltales, bottom, middle and top of the sail, will react the same to the sheet position. Once you have the correct twist (which will be different as a function of wind angle) you can then sheet to the telltales.

If you still have a flappy leech then your sail needs a recut. I’m no sailmaker but that sail doesn’t look old to me.

You may need to change the jib lead from close hauled to reaching. Set the car for close hauled and add in a barber haul line forward. Easing off to reach will require the lead to go forward and preferably out.

Re: What am I doing wrong?

Unfortunately you have discovered a flaw in the low cut self-tacking jib implementation. The lead needs to move outboard and forward to open the foot and close the leach.
That sail and sheeting system just aren't designed to sail that angle or any lower.

Some things to try or consider:
  • It looks like your sail has multiple clew attachment holes. Try the one closer to the leech. This may be better reaching but worse when going upwind.
  • Try partially rolling up the jib. If you can't move the lead, you can move the sail.
  • Rig up a jib outhaul to a toe rail.
  • Roll up the jib completely and use a reaching sail.
  • Use jib tracks instead of the self-tacking system.
  • A short whisker pole might be viable.
  • A longer track would help, but get in the way.
  • This is why some better self-tacking jibs have a jib boom. Better sail shape but more exciting jibes.

Re: What am I doing wrong?

The sail looks new. As a self tacking sail it will never work very well on a breach or broader angle of sail as you can’t shift the jib car angle forward or backward. To sail effectively at broader wind angles you will need a cruising code zero on a furler. Most Hanse’s sail with these now. You can tighten the leach as suggested by attaching the sheet higher on the clew board, but it will still be a compromise that won’t work very well but you will have less flapping of the leach (basically you are tightening the leach).
