I believe the ZBVI gig originated in the second half of the 90s. Before ZBVI, David ran an SSB weather net as he cruised the Caribbean with his wife and toddler daughter aboard Misstine. I first encountered him in the summer of '96 somewhere in Grenada or the Venezuelan islands.

He also published "The Concise Guide to Caribbean Weather". The 2nd edition lists Bob Nock (AKA Fat Hog Bob, RIP) as a co-author.

He did a great job holding down that barstool at Village Cay.
