For now, I have a muffler clamp supporting the gooseneck on the mast. Until I figure something else out or get good enough to do things quickly w/o needing it. For right now, I felt like I wanted to support the gooseneck so that I was not lifting as much weight with the halyard line. This way is easier to pull and things don't get as tangled up as I'm hauling up the halyard line as when I was doing it before all from the cockpit.
I already have a go pro mount that will clamp to the boom. I'll be trying that shortly.
