(FORTUNE Magazine) – POWER GOLF GURU

Henry Kravis, Charles Schwab, Ken Chenault, and David Rockefeller all go to one man to doctor their swings: Jim McLean. The $500-an-hour Miamian's skill has become legendary among the corporate jet set. His teaching style: analyze but don't overanalyze. And be direct about just how bad a swing looks. Though that can mean bruised egos, McLean, 53, says his clients get over it: "These people are used to getting results on the job. They want the same from their golf games." --DAVID RYNECKI

CHARIOTS OF POWER

At 36 feet and close to half a million dollars, the Hinckley Picnic Boat is, inch for inch, among the costliest boats in the world. What makes it the conveyance of choice is its propulsion system, which combines a jet drive, bow thruster, computer, and joystick. That means when you approach another tycoon's yacht, you needn't risk your dignity with a botched landing. You simply pull alongside and push the joystick; the boat slips sideways through the water until your fenders touch. --TIM SMITH

For sheer might, you can't beat the 543-horsepower twin-turbo V-12 Maybach 62 ($359,500). But for everyday motoring, the powerful prefer a Chevy Suburban outfitted with high-tech ceramic armor (above; $50,000, plus about $70,000 for the armoring). The color? Black, of course. --MELANIE SHANLEY

POWER MOVES

According to D.A. Benton, author of Executive Charisma, these gestures reveal a person with clout every time. --ALYNDA WHEAT

THE DOUBLE-HAND SHAKE When one powerful person meets another, he unleashes the two-handed grasp (a.k.a. the Clinton). Pumping motions follow.

THE ENTRANCE When powerful people stride into a room, they pause at the doorway. Says Benton: "It's the frame for the picture of power."

THE FREE HAND Only the little people BlackBerry. Top guns enter meetings unencumbered: "Their knowledge and confidence is in their head."

THE CEO SLOUCH The most powerful person in the room doesn't sit ramrod straight. He relaxes--even reclines. Posture is for underlings.

POWER PLUMAGE In these sober times, even the most iconoclastic moguls have adopted a more formal look--one that's startlingly similar across the genders. What's next: the return of the floppy bow tie? --M.S.

HIS

THE SHIRT A sassy spread-collar, French-cuffed model, like those by Brit invader Paul Smith ($190-$360), telegraphs flair.

THE TIE An understated Armani ($135) is best. (No fighting with the shirt.)

THE SUIT Elegantly slim, the superfine-wool, three-button Brioni ($4,295) in black or charcoal beats a roomier cut.

THE WATCH Patek Philippe. Vintage models command hundreds of thousands. New, they start around $10,000.

THE SHOES The truly powerful opt for made-to-measure John Lobbs ($3,500 and up); mere mortals can get a ready-to-wear version for less than $1,000.

HERS

THE JEWELRY Simple yet substantial earrings, like these quartz and 18-karat-gold ones from Gabrielle Sanchez ($790), go with everything.

THE SHIRT Carly and Meg (Whitman) favor brightly colored silk blouses, such as those by Armani ($695-$1,500).

THE SUIT Skirts can be less than comfy on those private-jet jaunts. The powerful wear pantsuits--often black wool crepe Jil Sanders ($1,660).

THE WATCH Again, Patek Philippe is the standard.

THE SHOES Here's where the power woman lets her style shine. Jimmy Choo pumps, $480.

POWER LUNCH Restaurants go in and out of style faster than pop singers, but when they're hot, they're where deals get done. Here are the places that the highest of high rollers call their culinary homes. --A.W.

FOUR SEASONS (New York) The ultimate power hot spot. Make it the Grill Room for lunch or the legendary Pool Room for dinner, and you're sure to spot a Bronfman, Kissinger, or Jordan (Vernon).

THE CAPITAL GRILLE (Washington, D.C.) A stone's throw from the Senate, this is the kind of lunch place where all the regulars know one another by name (they should; they're on C-SPAN every day).

THE IVY (Los Angeles) The cozy, French-Provincial-meets-Beverly-Hills setting--and the low-carb barbecue vegetable salad--draws celebrities and the studio moguls who hire them.

GIBSONS STEAKHOUSE (Chicago) This Gold Coast mainstay attracts Michael Jordan and local CEOs, plus out-of-towners like David Letterman and Jay Leno (though, we venture to say, not on the same night).

THE CHINA CLUB (Hong Kong) Nearly 2,000 of Hong Kong's elite call David Tang's dining club their spot, thanks to the 1930s-Shanghai ambiance and local delicacies like shark fin and abalone.

THE SQUARE (London) Chef Philip Howard's prix fixe lunch menus (£25, £35, and £55) lure moneymen to this two-Michelin-star Mayfair eatery. Just don't show up for dinner: The clientele then is--horrors--American tourists.
