Where does that line go and what does it do that is going down into the board well?

Also I noticed the diamonds go into the mast here. I'm assuming the mast is sealed above that point? Where do those diamonds attach at the bottom? And how do you adjust diamond tension?

I hope this all works out. I'm very concerned about it.

I used to hoist that 6.0 and H20 mast and they were a lot heavier.

I also really hope that the hoist hieght is not changed on the spin. That would be really disappointing. Our current kite already uses the entire hoist hieght without an inch to spare.
