An engineer and a mathematician are given a pan of cold water, and told to boil the water. They both put it on the stove, and boil it.
The next day they are given a pan full of warm water, and told to boil the water.
The engineer takes the pan, puts it on the stove, and boils it.
The mathematician takes the pan and empties it, and fills it with cold water.
He then says: "I've now reduced it to a previously solved problem." and walks out.

It distributes the load well and puts mostly sheer load on the screws/bolts/pop rivets attachments of the eye strap. The vang also slides nicely from jibe to jibe on the spectra.

I think if you marked it well while in place so that everything lined up, it wouldn't be too fiddly with just a slightly loose fit. You certainly would not have to worry about a GENEROUSLY oversized hole on your sleeve.

I have a bail attachment on my boom and I have not broken it yet. I think the bail attachment is pretty common. The 20:1 vang set up makes it easier to fine-tune the adjustment. I doubt that I ever pulled with 50 pounds of force, though I've never thought of measuring that. I certainly would not worry about the forces involved if you went with a bail. There are plenty of examples of people using that set up and not having problems.
K.C. Walker wrote:Okay, I see what Swiftsail is saying. That seems like a really easy way to go! That is, if the sleeve can handle the load while being backed up by the mast.
50# would require quite a "yank" and you'd feel in with smaller line. I just now tried it with a 30# weight and a smooth double braid line (1/4") and I had trouble holding it (tended to slipp).

Yes, I'm using approximately quarter inch line and it definitely does not feel like I'm tugging on it as compared to the mainsheet.
