The bolt was 2.5in, but they had accounted for a 3in bolt which was used at every competition, as far as I could tell, so they could not load block, and wingnut in the bolt
This year's rules do not specify a minimum length for the eyebolt, which means that building a design where you thread the shaft of the eyebolt through a hole in your boomilever runs the risk of having this happen - you encounter a legal test setup that doesn't leave space for you to insert your device between the loading block and the eye of the bolt.
I'm sure I've seen at least one setup this year with no spare space at all - the eye of the bolt was right up against the loading block, and there was maybe one thread protruding from the top of the wingnut.
I may as well note that I've seen some pretty chunky S-hooks in use - I've seen a few devices where the 1" eyebolt fit comfortably, but teams were struggling to get the S-hook in place. A maximum dimension is not specified for the S-hook and chain, and probably should be.
