Hal wrote another book called 'How to Sail Around the World' - another excellent book. In it he has the history of his boats - can't remember them all off hand, their first boat was built in the 70's (ish), but their latest boat was built for them in the 90's if I recall right.

A quick Google reveals he was born in 1927. The latest of his books, that I can see is not yet released - Handling Storms at Sea - due for release in Oct 2008 - so assume he's still around (unless its a re-release of an older book).
