I did not mean to suggest that they would move, just that they are not necessary in the present case nor necessarily better.The Swan 65 sloop I ran had padeyes on the boom for reef line ends. A hell of a lot more load than the OP picture - which looks like a J-105 boom. Those padeyes never moved a mm. Held on by 4 tapped bolts.
which might come in handy on a big ass swan, but not really necessary on a J92.They let you achieve a consistent reefed sail - the dead end is always in the same place. They let you rig a safety strop that is fixed on the boom. In fact you can set the strop & release the tension completely on the reef line.
Looks scary but makes sense.I have moved away from using a bowline and gone to using a timber hitch. it gives you unlimited ability to pull down and back, but can easily be undone no matter how much pressure it's been under. I was originally afraid it would shake out when not reefed but two of them made it to bermuda and back on my Freedom 45 last year.
