Dave,
Thanks for the kind word. It's 5.0 oz. Dacron. BRIGHT yellow. I paid $ 1050. The boat is a Nacra 5.5 SL.

Rolf,
Hope to take those pictures today but I cannot locate endcaps and the wind is non-existant anyway. Hopefully, this week before the lake freezes over. I will ask Dave about the leech line as well and post his answer. It's beautiful craftsmanship, by the way, in how this sail is put together.

Jake,
I can't see how you could use these battens and this strap and buckle system without endcaps. The width of the battens (1/2 inch) and the play in the pocket would allow easily for the batten to slip off the strap it seems to me. I would think you would have to have the strap go through a slot in the end cap to make the batten captive. I've been wrong before though!
