That's kinda funny... and sad, that someone would take tools to another person's boat and steal parts from it.
I had a similar (also kinda funny, but sad) event. On the last day of my return trip from this year's PNW rendezvous, I got enough breeze to make it worth unfurling my jib and... found that I didn't have a furling line. Instead, there was a small piece of cord tying my furling drum to the bow pulpit so the jib wouldn't unfurl. Someone had apparently decided they needed that 60 feet of line more than I did, and knew enough about boats to make it hard to notice.
Replaying the previous day or so, the only time I was off the boat long enough for that to happen was when I went to dinner at Roche Harbor... which means someone went onto my boat did it in the middle of a crowded marine in broad daylight. Urrrgh.
None of that means anything, except... I feel your pain.
