I threw the idea around in my early days on the Tornado. I beleive it was John Forbes who said he tried it and the loads were to great. Also gave the spinnaker extra purchase to pull the halyard through the cleat when you did notwant it to.
We had 1:2 purchase on the Hobie Tiger tack line (split system). When I tried it on the Tornado we trashed a couple of cleats. TA what's on Griffo's boat now?
I tried the 1:2 on the separate tack line. Way too much load.
The 2-line system also allows us to tweak on the luff shape.
And occasionally we can ease out the tack if we need to point a bit higher. I'm still playing with that option. I'm not sure I am using it to its fullest.
I did. It was fast (I timed myself doing it in 3 seconds). My crew had to pull really hard to get enough luff tension. The other problem is that there is a lot of extra halyard sitting around when the spinnaker is down because the retrieval line goes out more than the halyard goes in.
As a big strong dude in his 20's that like to fiddle with stuff, I would setup something like this if I was crew and make the retrieval end 1:2 as well.
If your crew is not huge, they will spend so time trying to pull the last little bit to get enough luff tension that it is slower than 1:1. Also, note that the cleat will have to take twice as much force.
I tried the 1:2 tack line on the Capricorn also but went away from it due to the load.
Griffo now has a seperate tackline 1:1 through a spinnlock, same as I had on the Cap.

Thats kind of what I expected.
