Main halyard attachment
The dead end of my main halyard (I have no Karver hook) was attached to the mast crane with a shackle. The hole was wearing out and it would be a matter of time for my halyard to come loose. I ordered a pin from Zspars that goes through all the plates of the mast crane. Luckily the holes were already available so I just had to put the pin in. Note that the karver hook setup is very different.
