Things I have learned from the beach whilst rigging....

For vertical creases

1) let off downhaul - Horizontal (speed) creases OK

2) Slacken tack strop (if yours is adjustable)

3) Bungee return on the downhaul block - A bit of bungee around the gooseneck tied to the downhaul block returning it up to a loose position when let off downhaul.

4) new sails have a bungee luff cord - also lessens luff tension

5) time - as the sail stretched the vertical creases become less of an issue (this should be number 1) really)

6) if you can be *rsed - adjust tension of the top two battes - can pull the sail out - But a hassel and I never really got the balance between no crease and ability to flop batten through with tacking in light airs

 

 

For outhaul

Bungee return along boom - Like other classes that use strop around the boom clews - eg Laser,Tera - Pulls the clew back along the boom when let the outhaul off.

 

outhaul strop tension and friction is worse with Kicker on - So adjust when kicker loosened 

I have read that when flattening the sail the Cunningham can be as effective as the vang. However when I do this I'm left with vertical wrinkles behind the mast. The solution should be go apply more outhaul and here is the point of my post. I find the strop does not slide on the boom and so both increasing and decreasing outhaul have little effect. Has anyone else had problems with this?
