At a garden party of pretty white yachts, the Northern Marine 57 would be the one with the 101st Airborne Division tattoo on its arm and its T-shirt sleeves rolled up. The rugged exterior, however, doesn't mean you'll be camping out. The interior is fitted with all the amenities that make sense on a yacht such as this-sophisticated electronics, entertainment systems and the latest appliances. You won't find suede headliners or blown-glass chandeliers aboard a 57, but that is not because Northern Marine is incapable of such flash. Clients who make the trek to the Northern Marine plant in Anacortes, Washington, want a serious voyaging yacht, not a Las Vegas penthouse.
