FYI, sadly: The Sailnet Beneteau and Catalina Lists have been abuzz
with perplexed postings from and consoling advice to the owner of a
brand new Beneteau 57, the only one so far delivered in the U.S., just
purchased last week, and which, during commissioning, vanished from
the dealer's dock [sic!].

It is said that the Coast Guard, the insurer, and other police
agenies, and marinas have been alerted and are of course looking but
so far to no avail.
