Personal Flotation Device (PFD)

For those interested in such things, here's the link to a similar PFD to that which we wore in the Zodiac dinghies.

This inflates automatically using CO2 cylinders, with manual back-up (pull yellow handle), and also mouth back-up (blow into tube). More expensive ($140?) than those bulky ones people don't wear when fishing or boating because they're too hot or uncomfortable, but hey, what's your life worth?
