On my Hunter 216 rigging I have replaced many of the Clevis pins with Ball-Lock Quick-Release pins...simply because I am a trailer sailor and fiddling with clevis pins and their cotter rings takes a lot of time. I have installed the Quick-Release pins where the shrouds attach to the chainplates and on the forestay. A friend in my club is concerned that they may not be strong enough (he said: "They are hollow!"). They may be hollow but my guess is that they are a tube with a rod sliding through the tube...meaning that they are "almost solid". But, now knowing how they are constructed, I am at a loss.Anybody have experience with strength issues when replacing Clevis pins with Quick Release pins?
