Wait a few more days and I'll put the full diagram and specs on this forum.

I'm currently building up my PC again and don't have Word installed yet. I made a document out of it a year ago. I will put it on the forum in its full.

You have indeed a 1:8 cascaded system.

I have a 1:12 cascaded system and it looks just like AHPC system from the outside. So no line running along side the mast. Everything is internal and the amount of line used is minimal. The difference between my system and that of AHPC is that I put the internal bar alot higher inside the mast. However, Greg mentioned to me that they would start using this system on the Taipans as well. I just don't know when or even if they are doing it already.

I fully agree with JC, this system rocks. I'm pulling 200 mm out of my mainsail without any sweat that is 8 inches. When I designed the system I asked a taipan sailor how much travell the downhaul needed. he said 150 mm from nothing to fully tensioned. I got 200 mm now and have power for more. Currently I can't pull any further as my boom is in the way. I also feel that I don't want to pull any more, At some point you'll rip your mainsail apart.

My setup can be reduced from 1;12 to 1;8 is excess line is a problem;

But for now I'm really impressed by how the mainsail luff just moves up when the downhaul is uncleated. The friction in the system is indeed really small, especially if you take care to use the optimal line in each stage.
