Sailing alone

It would appear that a singlehanded yachtsman has perished off the IOW this weekend. A yacht on passage from Poole to Chichester was found crashed into the south of the IOW, engine running and sail aloft. There is no sign of the skipper.
As I'm primarily a singlehanded sailer it does cause me to think what I ned to do to keep safe. I always wear my life jacket, and I have safety lines. As its difficult to run jack stays I have one clipped to the tabernacle and clip in before going forward.
I'm CG66 registered and always log my passage with HMCG via VHF. I'm in the process of adding a GPS antenna for my VHF so I can send emergency with position. I have a small dinghy which I can inflate afloat in 5 minutes. I'm configuring the reefing so I can do everything from the companionway. I tend to put in a reef when I first think about it.
What else can we do? I'm seriously tempted to get a McMurdo PLB.
