Best place to mount a GoPro that will need to be removed after the event?

[SailFastJ22]

I'd like to use my GoPro at an upcoming event where I chartered a J22. Any suggestions on where to mount it so that I don't damage the boat and it can be removed easily?

This is where I mount mine. First is a bracket on the back stay second is my head mount.

This is a video I shot this weekend using both. See if you like any of these mount positions.

I went looking for the forum rules to see if a youtube link was ok but I can't find it. If it is not allowed, I apologize for my ignorance and will delete it if instructed.
