Old salts grouse about modern aesthetics. It’s just what they do, and the hard lines and spartan interiors of today’s production boats give them many reasons to complain. French builder Wauquiez, however, seems to consistently be able to marry contemporary elements with more


Sights and Stories Cruising the Caribbean

Though I hate to think of myself as a “disaster tourist,” I can’t deny one of the things I was most curious about as I sailed south last fall to visit St. Martin, the Virgin Islands and Puerto Rico was how much hurricane damage I would see. I’m sure no one needs reminding that more
