Livingston had one on the boom once...I think he used a batten to extend the boom and mount the spot to. If memory serves me, I think the batten broke in a capsize or something and the spot was lost. I would be a little careful with the nuclear gybes but it's probably one of the better places for it.
For the Everglades challenge, we strapped the spot to the boom on the tri just in front of the mainsail strop. It seemed to work just fine from there.
We had ours on a batten on the boom of the 20 for a couple of tybees. Worked fine. If the jibe is so violent you make it go away the boom is probably gone too, unless you put it on with less than substantial stuff. I think anyone who wants to make me put stuff on my shoulders should get stuck under a tramp with said paraphernalia on and see if they still think it's a good idea. Been down that road and prefer not to go back.
