I'm looking for a quick release snap to use with an anchor line. The problem is that I don't trust anything I've seen so far. Snaps like this one can open up on their own unexpectedly. I once almost lost a kayak like this.
The only secure "snap" that I trust is the quick link.
But the problem with it is that eventually the threads will rust and the nut will seize. Plus it takes a little too long to secure for when doing it numerous times throughout the day.
