Jan,

You're on the right track, even the best tool is no good if it is not with you when you need it.

Just a thought, have you considered one of the new personal EPIRB's and/or PLB's that broadcast GPS position data as well as identifying the user it is assigned to? A bit pricey as yet, but...it is a high tech device and is already credited with several rescues. Please look at Doug's excellent commentary regarding these and their use.

Of course, if you're stuck in the rigging underwater, a knife will do more at the time to ensure survival. Perhaps getting a decent fixed blade and the Rescue Hook might be an alternative path. The knife could be worn in one manner and the hook in a different manner. If you're stuck in lines, you may not be able to reach one of the two...

Enjoy your anniversary, congratulations. <img src="images/graemlins/smile.gif" alt="" />
