After watching almost hours of video capture of happy owners blasting trough the waves, I have rarely (if ever) seen a birds's eye view from the tip of the mast looking downwards whilst under sail.
Some of the most dramatic footage I have ever shot was on my previously owned Catalina 27 sloop hoisted up on a bosun's chair and shooting handheld.
The camera system I use now has a remote control which looks like it is begging to shoot from the top of the mast.
