This is all well and good but it's not giving me any of the answers I'm looking for

Don't you use a seperate hound for the 2nd headsail halyard?

For my specific application: I have a G-Cat 5.7M and I want to run a r/f reacher on it. The spin poles will be a V shape arrangement coming off the bow x-beam (beam not foil)

I've attached a (very) rough sketch of what I want to do. I'll be using two lower windsurfer mast sections.
