At the top of the mast there is a screw going down the center. Surrounding the screw is washer, thrust bearing, bracket, thrust bearing and another washer. The bracket faces forward and the spinnaker and the jib halyard go up to blocks mounted on that bracket.
Assuming you can cleat the halyards off tightly, the mast will roll around and reef. Without the thrust bearings, the halyard sometimes wraps around the mainsail making a mess.
The software for the tracking stuff is all included in the camera, so even dummies like me can put the dashboard on the video. It is a Sony Action Cam AS100V. Thanks for the kudo's on the video. I am getting more experienced at making them.
