Yeah, 3.0 narrow width. The rotated panel in the luff is a much nicer (but harder) way to deal with the luff loads and the even transfer through the sail. The panel right on the luff is a bainbridge cloth, can't remember the name but its mainly uni carbon in a matrix.

I have seen sails with the carbon/pen tapes on the luff and I think the results have been mixed, some look a bit like the early 3DL sails where the fibres were not applied at even tensions and the sail bunched a little at the load points.

Battens are std fibrefoam Tornado, pretty soft, bottom 4 or so would be between 1.0kg up to 1.5kg top battens would be 2.3kg or so.

Boat is a modified Taipan 5.7, Mast is actually moulded off a Taipan 4.9 section and produced by Applied composites in Melbourne Australia.
