Shackle failure

[Refueler]

I use bowline on spinnaker sheets and halyard. Just make sure tail is long enough. Bowline omn halyard puts the wear point of halyard on sheavee at top ina different place each time so minimising chafe/wear. ol'will

As I said earlier ... Bowline is my go to ... you can as Will, make sure long tail - or just add a half hitch to stop tail from loosening the bowline.

I don't use Soft Shackles ... I stopped using Snap Shackles for anything that could result in injury (ie sheets to Genny) ....
