Some notes from my installation:
At about 9:45, I didn’t use a eye at the end of the line for exactly the reason they mention: you can’t change it or remove it. Since I was trailer-sailing at that time, I needed to remove the line when unstepping. So I just used a stopper knot on that end.
At about 11:43, I put that strap underneath the boom.
To tie off, I used a cleat that was already on the mast, so I didn’t have the cleat they discuss at about 13:20. I led the line under the rams head then up to the cleat on the mast.
I used aluminum rivets, not stainless. I realized stainless is stronger. Perhaps the aluminum will need to be replaced one day, but it’s easy enough to drill out an aluminum rivet and replace when needed… though that’s the new owner’s issue now!
Again, I used a long enough line that I could get the jacks cleaned up and out of the way to put on the boom cover. I brought both legs on each side back to the gooseneck and hooked them under the rams head hooks on each side of the gooseneck. I also cleaned up the jacks after raising the main so it didn’t affect sail shape.
At about 17:40, they discuss an option for shock cords off the spreaders to open up the slot. I didn’t do that either. As I said before, sometimes we had issues with the full sized battens getting hung up when raising the sail, but we were always ready to deal with that possibility.
