2nd outhaul cringle

[PabloPicasso]

There is a second outhaul cringle fitted to the mainsail, slighly above the actual outhaul.

Is that for a reefing line to help trim the sail, perhaps in conjuction with the cunnigham?

How do you judge efficent trim with this set up?

Probably a "flattener" reef point. It's a mini reef to flatten the sail. Leave the tack/cunningham alone (from memory), and wind on the flattener.

Not sure they're fitted much these says.

Nice if you need the boom a bit higher .
Some seem to have a luff Cringle and some don't.

They are used with attached foot sails that have a shelf foot. By attaching the outhaul above the shelf, it is easier to flatten the foot. Such a cringle serves no purpose on loose foot sails and sails without a pronounced shelf.

A cuningham (luff cringle) can help on any sail, because it allows tensioning of the bottom third of the sail, which could be supplied by halyard tension, but is often inhibited by tast track friction.

You also need something to pull the tack forward, or you can pull the sail out of the mast. Reefing horns are common, or sometimes the direction of pull of reefing lines. Sometimes a strap is helpful.

A s said it is a flattening reef. I would suggest you might like to fix the bottom normal clew pulled out to a small degree. (suitable for light winds) Then take your adjustable outhaul tackle to the flattening reef. So when wind comes up you haul on the tackle to pull the flattening reef down. Slightly reduces sail area but does remove much of the belly of the bottom of the main sail. ol'will
