EDICATION
The world of cruising is driven by dreamers. Dreamers design and
build the boats (otherwise they would be doing something more
profitable), and dreamers buy the products in hopes of fulfilling their
own vision—whether a weekend cruise or an open-ended circum-
navigation.
And while most boats sit tied to the dock, to be used only on occa-
sion, a very few actually head out towards the unknown. Perhaps it is
a two-week cruise to Martha’s Vineyard or the Channel Islands from
home port. Or maybe it’s to Mexico with thoughts of the South
Pacific. Wherever they sail, these folks are making their dreams
come true. And it is the “doers,” those making it happen, to whom we
dedicate
EDICATION
It wasn’t that many years ago
that sailors took pride in
their seamanship. It was
these skills, after all, which
kept them safe, helped them
to make a living, and
brought approval in the eyes
of their contemporaries.
Study this image of the
schooner Mariette, every
inch of her canvas set per-
fectly as she slides along on
a beam reach. She’s one of
Nathaniel Herreshoff’s won-
derful designs. Built in 1915,
when she’s reaching like this
there are few modern mega-
yachts which can sail with
her.
Her history and the way she
is handled today is an inspi-
ration to all modern sailors.
