I wanted to try and get some shots with the camera mounted above and/or away from the mast-head (for example with the top of the mast visible in the shot).
I attached a standard GoPro bike-frame mount to the mast-tip tube and mounted the camera on the end of two articulating arms:
In retrospect, I should have realized that using a light-weight plastic mount and cantilevering the camera on the end of a fairly long lever-arm maybe wasn't the greatest idea I've ever had.
The good news is the plastic held together for the runs, but just barely...
I beat my first one up pretty badly the first time I tried it (video), and it was also used to mount a camera to my blokart axle when I was plowing through tall weeds (video).
It seems to have suffered no ill effects from the abuse:
Here's a video from yesterday sailing around a 415' (126m) parking lot course.
I'm following the fellow who let me sail (and flip) his blokart many years ago.
This was his first time out in quite a while, and the first time he's ever sailed a 5.5m (thankfully he's a very good sailor, so my loaner sail survived the day without any luff tears!).
Sorry for the length.
Right at the end there are a couple of "full speed" laps around the course to give an idea of what it was like:
