Our was a DIY effort. Refer the photos on the earlier thread - link above.



We ordered a harken track curved 'ends up' @ 1.75m radius and 1m or 1.2m long (ours is 1m). We are using the smallest Harken track which was a big call at the time but it works fine. I suspect most people will use a bigger track.



We have anchored it with small spacers of 3/4" plastic rod and long model c'sunk pop rivets.



I made a mock-up of the SS ends and gave it to a clever engineer. Next time I would do carbon.



There are various methods of doing these things - some pivot (refer the Tornado website). I prefer to have it fixed so you don't lose any energy with movement when easing or tightening the jibsheet.



I don't know anything about Lars Guck's system but you should check that out to as it will no doubt have a lot of thought in it.
